      exercising permissions granted by this License.
       
      “Source” form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.
       
      “Object” form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.
       
      “Work” shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).
       
      “Derivative Works” shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.
       
      “Contribution” shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, “submitted”
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as “Not a Contribution.”
       
      “Contributor” shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.
       
      2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.
       
      3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.
       
      4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:
       
      (a) You must give any other recipients of the Work or
      Derivative Works a copy of this License; and
       
      (b) You must cause any modified files to carry prominent notices
      stating that You changed the files; and
       
      (c) You must retain, in the Source form of any Derivative Works
      that You distribute, all copyright, patent, trademark, and
      attribution notices from the Source form of the Work,
      excluding those notices that do not pertain to any part of
      the Derivative Works; and
       
      (d) If the Work includes a “NOTICE” text file as part of its
      distribution, then any Derivative Works that You distribute must
      include a readable copy of the attribution notices contained
      within such NOTICE file, excluding those notices that do not
      pertain to any part of the Derivative Works, in at least one
      of the following places: within a NOTICE text file distributed
      as part of the Derivative Works; within the Source form or
      documentation, if provided along with the Derivative Works; or,
      within a display generated by the Derivative Works, if and
      wherever such third-party notices normally appear. The contents
      of the NOTICE file are for informational purposes only and
      do not modify the License. You may add Your own attribution
      notices within Derivative Works that You distribute, alongside
      or as an addendum to the NOTICE text from the Work, provided
      that such additional attribution notices cannot be construed
      as modifying the License.
       
      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.
       
      5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.
       
      6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.
       
      7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an “AS IS” BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.
       
      8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.
       
      9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
       
      END OF TERMS AND CONDITIONS

      GCC RUNTIME LIBRARY EXCEPTION
       
      Version 3.1, 31 March 2009
       
      Copyright (C) 2009 Free Software Foundation, Inc. http://fsf.org/
       
      Everyone is permitted to copy and distribute verbatim copies of this
      license document, but changing it is not allowed.
       
      This GCC Runtime Library Exception (“Exception”) is an additional
      permission under section 7 of the GNU General Public License, version
      3 (“GPLv3”). It applies to a given file (the “Runtime Library”) that
      bears a notice placed by the copyright holder of the file stating that
      the file is governed by GPLv3 along with this Exception.
       
      When you use GCC to compile a program, GCC may combine portions of
      certain GCC header files and runtime libraries with the compiled
      program. The purpose of this Exception is to allow compilation of
      non-GPL (including proprietary) programs to use, in this way, the
      header files and runtime libraries covered by this Exception.
       
      0. Definitions.
       
      A file is an “Independent Module” if it either requires the Runtime
      Library for execution after a Compilation Process, or makes use of an
      interface provided by the Runtime Library, but is not otherwise based
      on the Runtime Library.
       
      “GCC” means a version of the GNU Compiler Collection, with or without
      modifications, governed by version 3 (or a specified later version) of
      the GNU General Public License (GPL) with the option of using any
      subsequent versions published by the FSF.
       
      “GPL-compatible Software” is software whose conditions of propagation,
      modification and use would permit combination with GCC in accord with
      the license of GCC.
       
      “Target Code” refers to output from any compiler for a real or virtual
      target processor architecture, in executable form or suitable for
      input to an assembler, loader, linker and/or execution
      phase. Notwithstanding that, Target Code does not include data in any
      format that is used as a compiler intermediate representation, or used
      for producing a compiler intermediate representation.
       
      The “Compilation Process” transforms code entirely represented in
      non-intermediate languages designed for human-written code, and/or in
      Java Virtual Machine byte code, into Target Code. Thus, for example,
      use of source code generators and preprocessors need not be considered
      part of the Compilation Process, since the Compilation Process can be
      understood as starting with the output of the generators or
      preprocessors.
       
      A Compilation Process is “Eligible” if it is done using GCC, alone or
      with other GPL-compatible software, or if it is done without using any
      work based on GCC. For example, using non-GPL-compatible Software to
      optimize any GCC intermediate representations would not qualify as an
      Eligible Compilation Process.
       
      1. Grant of Additional Permission.
       
      You have permission to propagate a work of Target Code formed by
      combining the Runtime Library with Independent Modules, even if such
      propagation would otherwise violate the terms of GPLv3, provided that
      all Target Code was generated by Eligible Compilation Processes. You
      may then convey such a combination under terms of your choice,
      consistent with the licensing of the Independent Modules.
       
      2. No Weakening of GCC Copyleft.
       
      The availability of this Exception does not imply any general
      presumption that third-party software is unaffected by the copyleft
      requirements of the license of GCC.
       
       
      GNU GENERAL PUBLIC LICENSE
      Version 3, 29 June 2007
       
      Copyright (C) 2007 Free Software Foundation, Inc. http://fsf.org/
      Everyone is permitted to copy and distribute verbatim copies
      of this license document, but changing it is not allowed.
       
      Preamble
       
      The GNU General Public License is a free, copyleft license for
      software and other kinds of works.
       
      The licenses for most software and other practical works are designed
      to take away your freedom to share and change the works. By contrast,
      the GNU General Public License is intended to guarantee your freedom to
      share and change all versions of a program–to make sure it remains free
      software for all its users. We, the Free Software Foundation, use the
      GNU General Public License for most of our software; it applies also to
      any other work released this way by its authors. You can apply it to
      your programs, too.
       
      When we speak of free software, we are referring to freedom, not
      price. Our General Public Licenses are designed to make sure that you
      have the freedom to distribute copies of free software (and charge for
      them if you wish), that you receive source code or can get it if you
      want it, that you can change the software or use pieces of it in new
      free programs, and that you know you can do these things.
       
      To protect your rights, we need to prevent others from denying you
      these rights or asking you to surrender the rights. Therefore, you have
      certain responsibilities if you distribute copies of the software, or if
      you modify it: responsibilities to respect the freedom of others.
       
      For example, if you distribute copies of such a program, whether
      gratis or for a fee, you must pass on to the recipients the same
      freedoms that you received. You must make sure that they, too, receive
      or can get the source code. And you must show them these terms so they
      know their rights.
       
      Developers that use the GNU GPL protect your rights with two steps:
      (1) assert copyright on the software, and (2) offer you this License
      giving you legal permission to copy, distribute and/or modify it.
       
      For the developers’ and authors’ protection, the GPL clearly explains
      that there is no warranty for this free software. For both users’ and
      authors’ sake, the GPL requires that modified versions be marked as
      changed, so that their problems will not be attributed erroneously to
      authors of previous versions.
       
      Some devices are designed to deny users access to install or run
      modified versions of the software inside them, although the manufacturer
      can do so. This is fundamentally incompatible with the aim of
      protecting users’ freedom to change the software. The systematic
      pattern of such abuse occurs in the area of products for individuals to
      use, which is precisely where it is most unacceptable. Therefore, we
      have designed this version of the GPL to prohibit the practice for those
      products. If such problems arise substantially in other domains, we
      stand ready to extend this provision to those domains in future versions
      of the GPL, as needed to protect the freedom of users.
       
      Finally, every program is threatened constantly by software patents.
      States should not allow patents to restrict development and use of
      software on general-purpose computers, but in those that do, we wish to
      avoid the special danger that patents applied to a free program could
      make it effectively proprietary. To prevent this, the GPL assures that
      patents cannot be used to render the program non-free.
       
      The precise terms and conditions for copying, distribution and
      modification follow.
       
      TERMS AND CONDITIONS
       
      0. Definitions.
       
      “This License” refers to version 3 of the GNU General Public License.
       
      “Copyright” also means copyright-like laws that apply to other kinds of
      works, such as semiconductor masks.
       
      “The Program” refers to any copyrightable work licensed under this
      License. Each licensee is addressed as “you”. “Licensees” and
      “recipients” may be individuals or organizations.
       
      To “modify” a work means to copy from or adapt all or part of the work
      in a fashion requiring copyright permission, other than the making of an
      exact copy. The resulting work is called a “modified version” of the
      earlier work or a work “based on” the earlier work.
       
      A “covered work” means either the unmodified Program or a work based
      on the Program.
       
      To “propagate” a work means to do anything with it that, without
      permission, would make you directly or secondarily liable for
      infringement under applicable copyright law, except executing it on a
      computer or modifying a private copy. Propagation includes copying,
      distribution (with or without modification), making available to the
      public, and in some countries other activities as well.
       
      To “convey” a work means any kind of propagation that enables other
      parties to make or receive copies. Mere interaction with a user through
      a computer network, with no transfer of a copy, is not conveying.
       
      An interactive user interface displays “Appropriate Legal Notices”
      to the extent that it includes a convenient and prominently visible
      feature that (1) displays an appropriate copyright notice, and (2)
      tells the user that there is no warranty for the work (except to the
      extent that warranties are provided), that licensees may convey the
      work under this License, and how to view a copy of this License. If
      the interface presents a list of user commands or options, such as a
      menu, a prominent item in the list meets this criterion.
       
      1. Source Code.
       
      The “source code” for a work means the preferred form of the work
      for making modifications to it. “Object code” means any non-source
      form of a work.
       
      A “Standard Interface” means an interface that either is an official
      standard defined by a recognized standards body, or, in the case of
      interfaces specified for a particular programming language, one that
      is widely used among developers working in that language.
       
      The “System Libraries” of an executable work include anything, other
      than the work as a whole, that (a) is included in the normal form of
      packaging a Major Component, but which is not part of that Major
      Component, and (b) serves only to enable use of the work with that
      Major Component, or to implement a Standard Interface for which an
      implementation is available to the public in source code form. A
      “Major Component”, in this context, means a major essential component
      (kernel, window system, and so on) of the specific operating system
      (if any) on which the executable work runs, or a compiler used to
      produce the work, or an object code interpreter used to run it.
       
      The “Corresponding Source” for a work in object code form means all
      the source code needed to generate, install, and (for an executable
      work) run the object code and to modify the work, including scripts to
      control those activities. However, it does not include the work’s
      System Libraries, or general-purpose tools or generally available free
      programs which are used unmodified in performing those activities but
      which are not part of the work. For example, Corresponding Source
      includes interface definition files associated with source files for
      the work, and the source code for shared libraries and dynamically
      linked subprograms that the work is specifically designed to require,
      such as by intimate data communication or control flow between those
      subprograms and other parts of the work.
       
      The Corresponding Source need not include anything that users
      can regenerate automatically from other parts of the Corresponding
      Source.
       
      The Corresponding Source for a work in source code form is that
      same work.
       
      2. Basic Permissions.
       
      All rights granted under this License are granted for the term of
      copyright on the Program, and are irrevocable provided the stated
      conditions are met. This License explicitly affirms your unlimited
      permission to run the unmodified Program. The output from running a
      covered work is covered by this License only if the output, given its
      content, constitutes a covered work. This License acknowledges your
      rights of fair use or other equivalent, as provided by copyright law.
       
      You may make, run and propagate covered works that you do not
      convey, without conditions so long as your license otherwise remains
      in force. You may convey covered works to others for the sole purpose
      of having them make modifications exclusively for you, or provide you
      with facilities for running those works, provided that you comply with
      the terms of this License in conveying all material for which you do
      not control copyright. Those thus making or running the covered works
      for you must do so exclusively on your behalf, under your direction
      and control, on terms that prohibit them from making any copies of
      your copyrighted material outside their relationship with you.
       
      Conveying under any other circumstances is permitted solely under
      the conditions stated below. Sublicensing is not allowed; section 10
      makes it unnecessary.
       
      3. Protecting Users’ Legal Rights From Anti-Circumvention Law.
       
      No covered work shall be deemed part of an effective technological
      measure under any applicable law fulfilling obligations under article
      11 of the WIPO copyright treaty adopted on 20 December 1996, or
      similar laws prohibiting or restricting circumvention of such
      measures.
       
      When you convey a covered work, you waive any legal power to forbid
      circumvention of technological measures to the extent such circumvention
      is effected by exercising rights under this License with respect to
      the covered work, and you disclaim any intention to limit operation or
      modification of the work as a means of enforcing, against the work’s
      users, your or third parties’ legal rights to forbid circumvention of
      technological measures.
       
      4. Conveying Verbatim Copies.
       
      You may convey verbatim copies of the Program’s source code as you
      receive it, in any medium, provided that you conspicuously and
      appropriately publish on each copy an appropriate copyright notice;
      keep intact all notices stating that this License and any
      non-permissive terms added in accord with section 7 apply to the code;
      keep intact all notices of the absence of any warranty; and give all
      recipients a copy of this License along with the Program.
       
      You may charge any price or no price for each copy that you convey,
      and you may offer support or warranty protection for a fee.
       
      5. Conveying Modified Source Versions.
       
      You may convey a work based on the Program, or the modifications to
      produce it from the Program, in the form of source code under the
      terms of section 4, provided that you also meet all of these conditions:
       
      a) The work must carry prominent notices stating that you modified
      it, and giving a relevant date.
       
      b) The work must carry prominent notices stating that it is
      released under this License and any conditions added under section
      7. This requirement modifies the requirement in section 4 to
      “keep intact all notices”.
       
      c) You must license the entire work, as a whole, under this
      License to anyone who comes into possession of a copy. This
      License will therefore apply, along with any applicable section 7
      additional terms, to the whole of the work, and all its parts,
      regardless of how they are packaged. This License gives no
      permission to license the work in any other way, but it does not
      invalidate such permission if you have separately received it.
       
      d) If the work has interactive user interfaces, each must display
      Appropriate Legal Notices; however, if the Program has interactive
      interfaces that do not display Appropriate Legal Notices, your
      work need not make them do so.
       
      A compilation of a covered work with other separate and independent
      works, which are not by their nature extensions of the covered work,
      and which are not combined with it such as to form a larger program,
      in or on a volume of a storage or distribution medium, is called an
      “aggregate” if the compilation and its resulting copyright are not
      used to limit the access or legal rights of the compilation’s users
      beyond what the individual works permit. Inclusion of a covered work
      in an aggregate does not cause this License to apply to the other
      parts of the aggregate.
       
      6. Conveying Non-Source Forms.
       
      You may convey a covered work in object code form under the terms
      of sections 4 and 5, provided that you also convey the
      machine-readable Corresponding Source under the terms of this License,
      in one of these ways:
       
      a) Convey the object code in, or embodied in, a physical product
      (including a physical distribution medium), accompanied by the
      Corresponding Source fixed on a durable physical medium
      customarily used for software interchange.
       
      b) Convey the object code in, or embodied in, a physical product
      (including a physical distribution medium), accompanied by a
      written offer, valid for at least three years and valid for as
      long as you offer spare parts or customer support for that product
      model, to give anyone who possesses the object code either (1) a
      copy of the Corresponding Source for all the software in the
      product that is covered by this License, on a durable physical
      medium customarily used for software interchange, for a price no
      more than your reasonable cost of physically performing this
      conveying of source, or (2) access to copy the
      Corresponding Source from a network server at no charge.
       
      c) Convey individual copies of the object code with a copy of the
      written offer to provide the Corresponding Source. This
      alternative is allowed only occasionally and noncommercially, and
      only if you received the object code with such an offer, in accord
      with subsection 6b.
       
      d) Convey the object code by offering access from a designated
      place (gratis or for a charge), and offer equivalent access to the
      Corresponding Source in the same way through the same place at no
      further charge. You need not require recipients to copy the
      Corresponding Source along with the object code. If the place to
      copy the object code is a network server, the Corresponding Source
      may be on a different server (operated by you or a third party)
      that supports equivalent copying facilities, provided you maintain
      clear directions next to the object code saying where to find the
      Corresponding Source. Regardless of what server hosts the
      Corresponding Source, you remain obligated to ensure that it is
      available for as long as needed to satisfy these requirements.
       
      e) Convey the object code using peer-to-peer transmission, provided
      you inform other peers where the object code and Corresponding
      Source of the work are being offered to the general public at no
      charge under subsection 6d.
       
      A separable portion of the object code, whose source code is excluded
      from the Corresponding Source as a System Library, need not be
      included in conveying the object code work.
       
      A “User Product” is either (1) a “consumer product”, which means any
      tangible personal property which is normally used for personal, family,
      or household purposes, or (2) anything designed or sold for incorporation
      into a dwelling. In determining whether a product is a consumer product,
      doubtful cases shall be resolved in favor of coverage. For a particular
      product received by a particular user, “normally used” refers to a
      typical or common use of that class of product, regardless of the status
      of the particular user or of the way in which the particular user
      actually uses, or expects or is expected to use, the product. A product
      is a consumer product regardless of whether the product has substantial
      commercial, industrial or non-consumer uses, unless such uses represent
      the only significant mode of use of the product.
       
      “Installation Information” for a User Product means any methods,
      procedures, authorization keys, or other information required to install
      and execute modified versions of a covered work in that User Product from
      a modified version of its Corresponding Source. The information must
      suffice to ensure that the continued functioning of the modified object
      code is in no case prevented or interfered with solely because
      modification has been made.
       
      If you convey an object code work under this section in, or with, or
      specifically for use in, a User Product, and the conveying occurs as
      part of a transaction in which the right of possession and use of the
      User Product is transferred to the recipient in perpetuity or for a
      fixed term (regardless of how the transaction is characterized), the
      Corresponding Source conveyed under this section must be accompanied
      by the Installation Information. But this requirement does not apply
      if neither you nor any third party retains the ability to install
      modified object code on the User Product (for example, the work has
      been installed in ROM).
       
      The requirement to provide Installation Information does not include a
      requirement to continue to provide support service, warranty, or updates
      for a work that has been modified or installed by the recipient, or for
      the User Product in which it has been modified or installed. Access to a
      network may be denied when the modification itself materially and
      adversely affects the operation of the network or violates the rules and
      protocols for communication across the network.
       
      Corresponding Source conveyed, and Installation Information provided,
      in accord with this section must be in a format that is publicly
      documented (and with an implementation available to the public in
      source code form), and must require no special password or key for
      unpacking, reading or copying.
       
      7. Additional Terms.
       
      “Additional permissions” are terms that supplement the terms of this
      License by making exceptions from one or more of its conditions.
      Additional permissions that are applicable to the entire Program shall
      be treated as though they were included in this License, to the extent
      that they are valid under applicable law. If additional permissions
      apply only to part of the Program, that part may be used separately
      under those permissions, but the entire Program remains governed by
      this License without regard to the additional permissions.
       
      When you convey a copy of a covered work, you may at your option
      remove any additional permissions from that copy, or from any part of
      it. (Additional permissions may be written to require their own
      removal in certain cases when you modify the work.) You may place
      additional permissions on material, added by you to a covered work,
      for which you have or can give appropriate copyright permission.
       
      Notwithstanding any other provision of this License, for material you
      add to a covered work, you may (if authorized by the copyright holders of
      that material) supplement the terms of this License with terms:
       
      a) Disclaiming warranty or limiting liability differently from the
      terms of sections 15 and 16 of this License; or
       
      b) Requiring preservation of specified reasonable legal notices or
      author attributions in that material or in the Appropriate Legal
      Notices displayed by works containing it; or
       
      c) Prohibiting misrepresentation of the origin of that material, or
      requiring that modified versions of such material be marked in
      reasonable ways as different from the original version; or
       
      d) Limiting the use for publicity purposes of names of licensors or
      authors of the material; or
       
      e) Declining to grant rights under trademark law for use of some
      trade names, trademarks, or service marks; or
       
      f) Requiring indemnification of licensors and authors of that
      material by anyone who conveys the material (or modified versions of
      it) with contractual assumptions of liability to the recipient, for
      any liability that these contractual assumptions directly impose on
      those licensors and authors.
       
      All other non-permissive additional terms are considered “further
      restrictions” within the meaning of section 10. If the Program as you
      received it, or any part of it, contains a notice stating that it is
      governed by this License along with a term that is a further
      restriction, you may remove that term. If a license document contains
      a further restriction but permits relicensing or conveying under this
      License, you may add to a covered work material governed by the terms
      of that license document, provided that the further restriction does
      not survive such relicensing or conveying.
       
      If you add terms to a covered work in accord with this section, you
      must place, in the relevant source files, a statement of the
      additional terms that apply to those files, or a notice indicating
      where to find the applicable terms.
       
      Additional terms, permissive or non-permissive, may be stated in the
      form of a separately written license, or stated as exceptions;
      the above requirements apply either way.
       
      8. Termination.
       
      You may not propagate or modify a covered work except as expressly
      provided under this License. Any attempt otherwise to propagate or
      modify it is void, and will automatically terminate your rights under
      this License (including any patent licenses granted under the third
      paragraph of section 11).
       
      However, if you cease all violation of this License, then your
      license from a particular copyright holder is reinstated (a)
      provisionally, unless and until the copyright holder explicitly and
      finally terminates your license, and (b) permanently, if the copyright
      holder fails to notify you of the violation by some reasonable means
      prior to 60 days after the cessation.
       
      Moreover, your license from a particular copyright holder is
      reinstated permanently if the copyright holder notifies you of the
      violation by some reasonable means, this is the first time you have
      received notice of violation of this License (for any work) from that
      copyright holder, and you cure the violation prior to 30 days after
      your receipt of the notice.
       
      Termination of your rights under this section does not terminate the
      licenses of parties who have received copies or rights from you under
      this License. If your rights have been terminated and not permanently
      reinstated, you do not qualify to receive new licenses for the same
      material under section 10.
       
      9. Acceptance Not Required for Having Copies.
       
      You are not required to accept this License in order to receive or
      run a copy of the Program. Ancillary propagation of a covered work
      occurring solely as a consequence of using peer-to-peer transmission
      to receive a copy likewise does not require acceptance. However,
      nothing other than this License grants you permission to propagate or
      modify any covered work. These actions infringe copyright if you do
      not accept this License. Therefore, by modifying or propagating a
      covered work, you indicate your acceptance of this License to do so.
       
      10. Automatic Licensing of Downstream Recipients.
       
      Each time you convey a covered work, the recipient automatically
      receives a license from the original licensors, to run, modify and
      propagate that work, subject to this License. You are not responsible
      for enforcing compliance by third parties with this License.
       
      An “entity transaction” is a transaction transferring control of an
      organization, or substantially all assets of one, or subdividing an
      organization, or merging organizations. If propagation of a covered
      work results from an entity transaction, each party to that
      transaction who receives a copy of the work also receives whatever
      licenses to the work the party’s predecessor in interest had or could
      give under the previous paragraph, plus a right to possession of the
      Corresponding Source of the work from the predecessor in interest, if
      the predecessor has it or can get it with reasonable efforts.
       
      You may not impose any further restrictions on the exercise of the
      rights granted or affirmed under this License. For example, you may
      not impose a license fee, royalty, or other charge for exercise of
      rights granted under this License, and you may not initiate litigation
      (including a cross-claim or counterclaim in a lawsuit) alleging that
      any patent claim is infringed by making, using, selling, offering for
      sale, or importing the Program or any portion of it.
       
      11. Patents.
       
      A “contributor” is a copyright holder who authorizes use under this
      License of the Program or a work on which the Program is based. The
      work thus licensed is called the contributor’s “contributor version”.
       
      A contributor’s “essential patent claims” are all patent claims
      owned or controlled by the contributor, whether already acquired or
      hereafter acquired, that would be infringed by some manner, permitted
      by this License, of making, using, or selling its contributor version,
      but do not include claims that would be infringed only as a
      consequence of further modification of the contributor version. For
      purposes of this definition, “control” includes the right to grant
      patent sublicenses in a manner consistent with the requirements of
      this License.
       
      Each contributor grants you a non-exclusive, worldwide, royalty-free
      patent license under the contributor’s essential patent claims, to
      make, use, sell, offer for sale, import and otherwise run, modify and
      propagate the contents of its contributor version.
       
      In the following three paragraphs, a “patent license” is any express
      agreement or commitment, however denominated, not to enforce a patent
      (such as an express permission to practice a patent or covenant not to
      sue for patent infringement). To “grant” such a patent license to a
      party means to make such an agreement or commitment not to enforce a
      patent against the party.
       
      If you convey a covered work, knowingly relying on a patent license,
      and the Corresponding Source of the work is not available for anyone
      to copy, free of charge and under the terms of this License, through a
      publicly available network server or other readily accessible means,
      then you must either (1) cause the Corresponding Source to be so
      available, or (2) arrange to deprive yourself of the benefit of the
      patent license for this particular work, or (3) arrange, in a manner
      consistent with the requirements of this License, to extend the patent
      license to downstream recipients. “Knowingly relying” means you have
      actual knowledge that, but for the patent license, your conveying the
      covered work in a country, or your recipient’s use of the covered work
      in a country, would infringe one or more identifiable patents in that
      country that you have reason to believe are valid.
       
      If, pursuant to or in connection with a single transaction or
      arrangement, you convey, or propagate by procuring conveyance of, a
      covered work, and grant a patent license to some of the parties
      receiving the covered work authorizing them to use, propagate, modify
      or convey a specific copy of the covered work, then the patent license
      you grant is automatically extended to all recipients of the covered
      work and works based on it.
       
      A patent license is “discriminatory” if it does not include within
      the scope of its coverage, prohibits the exercise of, or is
      conditioned on the non-exercise of one or more of the rights that are
      specifically granted under this License. You may not convey a covered
      work if you are a party to an arrangement with a third party that is
      in the business of distributing software, under which you make payment
      to the third party based on the extent of your activity of conveying
      the work, and under which the third party grants, to any of the
      parties who would receive the covered work from you, a discriminatory
      patent license (a) in connection with copies of the covered work
      conveyed by you (or copies made from those copies), or (b) primarily
      for and in connection with specific products or compilations that
      contain the covered work, unless you entered into that arrangement,
      or that patent license was granted, prior to 28 March 2007.
       
      Nothing in this License shall be construed as excluding or limiting
      any implied license or other defenses to infringement that may
      otherwise be available to you under applicable patent law.
       
      12. No Surrender of Others’ Freedom.
       
      If conditions are imposed on you (whether by court order, agreement or
      otherwise) that contradict the conditions of this License, they do not
      excuse you from the conditions of this License. If you cannot convey a
      covered work so as to satisfy simultaneously your obligations under this
      License and any other pertinent obligations, then as a consequence you may
      not convey it at all. For example, if you agree to terms that obligate you
      to collect a royalty for further conveying from those to whom you convey
      the Program, the only way you could satisfy both those terms and this
      License would be to refrain entirely from conveying the Program.
       
      13. Use with the GNU Affero General Public License.
       
      Notwithstanding any other provision of this License, you have
      permission to link or combine any covered work with a work licensed
      under version 3 of the GNU Affero General Public License into a single
      combined work, and to convey the resulting work. The terms of this
      License will continue to apply to the part which is the covered work,
      but the special requirements of the GNU Affero General Public License,
      section 13, concerning interaction through a network will apply to the
      combination as such.
       
      14. Revised Versions of this License.
       
      The Free Software Foundation may publish revised and/or new versions of
      the GNU General Public License from time to time. Such new versions will
      be similar in spirit to the present version, but may differ in detail to
      address new problems or concerns.
       
      Each version is given a distinguishing version number. If the
      Program specifies that a certain numbered version of the GNU General
      Public License “or any later version” applies to it, you have the
      option of following the terms and conditions either of that numbered
      version or of any later version published by the Free Software
      Foundation. If the Program does not specify a version number of the
      GNU General Public License, you may choose any version ever published
      by the Free Software Foundation.
       
      If the Program specifies that a proxy can decide which future
      versions of the GNU General Public License can be used, that proxy’s
      public statement of acceptance of a version permanently authorizes you
      to choose that version for the Program.
       
      Later license versions may give you additional or different
      permissions. However, no additional obligations are imposed on any
      author or copyright holder as a result of your choosing to follow a
      later version.
       
      15. Disclaimer of Warranty.
       
      THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
      APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
      HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY
      OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
      THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
      PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
      IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
      ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
       
      16. Limitation of Liability.
       
      IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
      WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
      THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
      GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
      USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
      DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
      PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
      EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
      SUCH DAMAGES.
       
      17. Interpretation of Sections 15 and 16.
       
      If the disclaimer of warranty and limitation of liability provided
      above cannot be given local legal effect according to their terms,
      reviewing courts shall apply local law that most closely approximates
      an absolute waiver of all civil liability in connection with the
      Program, unless a warranty or assumption of liability accompanies a
      copy of the Program in return for a fee.
       
      END OF TERMS AND CONDITIONS
       
      How to Apply These Terms to Your New Programs
       
      If you develop a new program, and you want it to be of the greatest
      possible use to the public, the best way to achieve this is to make it
      free software which everyone can redistribute and change under these terms.
       
      To do so, attach the following notices to the program. It is safest
      to attach them to the start of each source file to most effectively
      state the exclusion of warranty; and each file should have at least
      the “copyright” line and a pointer to where the full notice is found.
       
      <one line to give the program’s name and a brief idea of what it does.>
      Copyright (C)
       
      This program is free software: you can redistribute it and/or modify
      it under the terms of the GNU General Public License as published by
      the Free Software Foundation, either version 3 of the License, or
      (at your option) any later version.
       
      This program is distributed in the hope that it will be useful,
      but WITHOUT ANY WARRANTY; without even the implied warranty of
      MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
      GNU General Public License for more details.
       
      You should have received a copy of the GNU General Public License
      along with this program. If not, see http://www.gnu.org/licenses/.
       
      Also add information on how to contact you by electronic and paper mail.
       
      If the program does terminal interaction, make it output a short
      notice like this when it starts in an interactive mode:
       
      Copyright (C)
      This program comes with ABSOLUTELY NO WARRANTY; for details type `show w’.
      This is free software, and you are welcome to redistribute it
      under certain conditions; type `show c’ for details.
       
      The hypothetical commands show w' and show c’ should show the appropriate
      parts of the General Public License. Of course, your program’s commands
      might be different; for a GUI interface, you would use an “about box”.
       
      You should also get your employer (if you work as a programmer) or school,
      if any, to sign a “copyright disclaimer” for the program, if necessary.
      For more information on this, and how to apply and follow the GNU GPL, see
      http://www.gnu.org/licenses/.
       
      The GNU General Public License does not permit incorporating your program
      into proprietary programs. If your program is a subroutine library, you
      may consider it more useful to permit linking proprietary applications with
      the library. If this is what you want to do, use the GNU Lesser General
      Public License instead of this License. But first, please read

      “Derivative Works” shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      designated in writing by the copyright owner as “Not a Contribution.”
       
      “Contributor” shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.
       
      2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.
       
      3. Grant of Patent License. Subject to the terms and conditions of

      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.
       
      4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:
       
      (a) You must give any other recipients of the Work or
      Derivative Works a copy of this License; and
       
      (b) You must cause any modified files to carry prominent notices
      stating that You changed the files; and
       
      (c) You must retain, in the Source form of any Derivative Works
      that You distribute, all copyright, patent, trademark, and
      attribution notices from the Source form of the Work,
      excluding those notices that do not pertain to any part of
      the Derivative Works; and
       
      (d) If the Work includes a “NOTICE” text file as part of its
      distribution, then any Derivative Works that You distribute must
      include a readable copy of the attribution notices contained
      within such NOTICE file, excluding those notices that do not
      pertain to any part of the Derivative Works, in at least one
      of the following places: within a NOTICE text file distributed
      as part of the Derivative Works; within the Source form or
      documentation, if provided along with the Derivative Works; or,
      within a display generated by the Derivative Works, if and
      wherever such third-party notices normally appear. The contents
      of the NOTICE file are for informational purposes only and
      do not modify the License. You may add Your own attribution
      notices within Derivative Works that You distribute, alongside
      or as an addendum to the NOTICE text from the Work, provided
      that such additional attribution notices cannot be construed
      as modifying the License.
       
      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.
       
      5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.
       
      6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.
       
      7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an “AS IS” BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.
       
      8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.
       
      9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

      GNU LESSER GENERAL PUBLIC LICENSE
      Version 2.1, February 1999
       
      Copyright (C) 1991, 1999 Free Software Foundation, Inc.
      51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
      Everyone is permitted to copy and distribute verbatim copies
      of this license document, but changing it is not allowed.
       
      [This is the first released version of the Lesser GPL. It also counts
      as the successor of the GNU Library Public License, version 2, hence
      the version number 2.1.]
       
      Preamble
       
      The licenses for most software are designed to take away your
      freedom to share and change it. By contrast, the GNU General Public
      Licenses are intended to guarantee your freedom to share and change
      free software–to make sure the software is free for all its users.
       
      This license, the Lesser General Public License, applies to some
      specially designated software packages–typically libraries–of the
      Free Software Foundation and other authors who decide to use it. You
      can use it too, but we suggest you first think carefully about whether
      this license or the ordinary General Public License is the better
      strategy to use in any particular case, based on the explanations below.
       
      When we speak of free software, we are referring to freedom of use,
      not price. Our General Public Licenses are designed to make sure that
      you have the freedom to distribute copies of free software (and charge
      for this service if you wish); that you receive source code or can get
      it if you want it; that you can change the software and use pieces of
      it in new free programs; and that you are informed that you can do
      these things.
       
      To protect your rights, we need to make restrictions that forbid
      distributors to deny you these rights or to ask you to surrender these
      rights. These restrictions translate to certain responsibilities for
      you if you distribute copies of the library or if you modify it.
       
      For example, if you distribute copies of the library, whether gratis
      or for a fee, you must give the recipients all the rights that we gave
      you. You must make sure that they, too, receive or can get the source
      code. If you link other code with the library, you must provide
      complete object files to the recipients, so that they can relink them
      with the library after making changes to the library and recompiling
      it. And you must show them these terms so they know their rights.
       
      We protect your rights with a two-step method: (1) we copyright the
      library, and (2) we offer you this license, which gives you legal
      permission to copy, distribute and/or modify the library.
       
      To protect each distributor, we want to make it very clear that
      there is no warranty for the free library. Also, if the library is
      modified by someone else and passed on, the recipients should know
      that what they have is not the original version, so that the original
      author’s reputation will not be affected by problems that might be
      introduced by others.
       
      Finally, software patents pose a constant threat to the existence of
      any free program. We wish to make sure that a company cannot
      effectively restrict the users of a free program by obtaining a
      restrictive license from a patent holder. Therefore, we insist that
      any patent license obtained for a version of the library must be
      consistent with the full freedom of use specified in this license.
       
      Most GNU software, including some libraries, is covered by the
      ordinary GNU General Public License. This license, the GNU Lesser
      General Public License, applies to certain designated libraries, and
      is quite different from the ordinary General Public License. We use
      this license for certain libraries in order to permit linking those
      libraries into non-free programs.
       
      When a program is linked with a library, whether statically or using
      a shared library, the combination of the two is legally speaking a
      combined work, a derivative of the original library. The ordinary
      General Public License therefore permits such linking only if the
      entire combination fits its criteria of freedom. The Lesser General
      Public License permits more lax criteria for linking other code with
      the library.
       
      We call this license the “Lesser” General Public License because it
      does Less to protect the user’s freedom than the ordinary General
      Public License. It also provides other free software developers Less
      of an advantage over competing non-free programs. These disadvantages
      are the reason we use the ordinary General Public License for many
      libraries. However, the Lesser license provides advantages in certain
      special circumstances.
       
      For example, on rare occasions, there may be a special need to
      encourage the widest possible use of a certain library, so that it becomes
      a de-facto standard. To achieve this, non-free programs must be
      allowed to use the library. A more frequent case is that a free
      library does the same job as widely used non-free libraries. In this
      case, there is little to gain by limiting the free library to free
      software only, so we use the Lesser General Public License.
       
      In other cases, permission to use a particular library in non-free
      programs enables a greater number of people to use a large body of
      free software. For example, permission to use the GNU C Library in
      non-free programs enables many more people to use the whole GNU
      operating system, as well as its variant, the GNU/Linux operating
      system.
       
      Although the Lesser General Public License is Less protective of the
      users’ freedom, it does ensure that the user of a program that is
      linked with the Library has the freedom and the wherewithal to run
      that program using a modified version of the Library.
       
      The precise terms and conditions for copying, distribution and
      modification follow. Pay close attention to the difference between a
      “work based on the library” and a “work that uses the library”. The
      former contains code derived from the library, whereas the latter must
      be combined with the library in order to run.
       
      GNU LESSER GENERAL PUBLIC LICENSE
      TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
       
      0. This License Agreement applies to any software library or other
      program which contains a notice placed by the copyright holder or
      other authorized party saying it may be distributed under the terms of
      this Lesser General Public License (also called “this License”).
      Each licensee is addressed as “you”.
       
      A “library” means a collection of software functions and/or data
      prepared so as to be conveniently linked with application programs
      (which use some of those functions and data) to form executables.
       
      The “Library”, below, refers to any such software library or work
      which has been distributed under these terms. A “work based on the
      Library” means either the Library or any derivative work under
      copyright law: that is to say, a work containing the Library or a
      portion of it, either verbatim or with modifications and/or translated
      straightforwardly into another language. (Hereinafter, translation is
      included without limitation in the term “modification”.)
       
      “Source code” for a work means the preferred form of the work for
      making modifications to it. For a library, complete source code means
      all the source code for all modules it contains, plus any associated
      interface definition files, plus the scripts used to control compilation
      and installation of the library.
       
      Activities other than copying, distribution and modification are not
      covered by this License; they are outside its scope. The act of
      running a program using the Library is not restricted, and output from
      such a program is covered only if its contents constitute a work based
      on the Library (independent of the use of the Library in a tool for
      writing it). Whether that is true depends on what the Library does
      and what the program that uses the Library does.
       
      1. You may copy and distribute verbatim copies of the Library’s
      complete source code as you receive it, in any medium, provided that
      you conspicuously and appropriately publish on each copy an
      appropriate copyright notice and disclaimer of warranty; keep intact
      all the notices that refer to this License and to the absence of any
      warranty; and distribute a copy of this License along with the
      Library.
       
      You may charge a fee for the physical act of transferring a copy,
      and you may at your option offer warranty protection in exchange for a
      fee.
       
      2. You may modify your copy or copies of the Library or any portion
      of it, thus forming a work based on the Library, and copy and
      distribute such modifications or work under the terms of Section 1
      above, provided that you also meet all of these conditions:
       
      a) The modified work must itself be a software library.
       
      b) You must cause the files modified to carry prominent notices
      stating that you changed the files and the date of any change.
       
      c) You must cause the whole of the work to be licensed at no
      charge to all third parties under the terms of this License.
       
      d) If a facility in the modified Library refers to a function or a
      table of data to be supplied by an application program that uses
      the facility, other than as an argument passed when the facility
      is invoked, then you must make a good faith effort to ensure that,
      in the event an application does not supply such function or
      table, the facility still operates, and performs whatever part of
      its purpose remains meaningful.
       
      (For example, a function in a library to compute square roots has
      a purpose that is entirely well-defined independent of the
      application. Therefore, Subsection 2d requires that any
      application-supplied function or table used by this function must
      be optional: if the application does not supply it, the square
      root function must still compute square roots.)
       
      These requirements apply to the modified work as a whole. If
      identifiable sections of that work are not derived from the Library,
      and can be reasonably considered independent and separate works in
      themselves, then this License, and its terms, do not apply to those
      sections when you distribute them as separate works. But when you
      distribute the same sections as part of a whole which is a work based
      on the Library, the distribution of the whole must be on the terms of
      this License, whose permissions for other licensees extend to the
      entire whole, and thus to each and every part regardless of who wrote
      it.
       
      Thus, it is not the intent of this section to claim rights or contest
      your rights to work written entirely by you; rather, the intent is to
      exercise the right to control the distribution of derivative or
      collective works based on the Library.
       
      In addition, mere aggregation of another work not based on the Library
      with the Library (or with a work based on the Library) on a volume of
      a storage or distribution medium does not bring the other work under
      the scope of this License.
       
      3. You may opt to apply the terms of the ordinary GNU General Public
      License instead of this License to a given copy of the Library. To do
      this, you must alter all the notices that refer to this License, so
      that they refer to the ordinary GNU General Public License, version 2,
      instead of to this License. (If a newer version than version 2 of the
      ordinary GNU General Public License has appeared, then you can specify
      that version instead if you wish.) Do not make any other change in
      these notices.
       
      Once this change is made in a given copy, it is irreversible for
      that copy, so the ordinary GNU General Public License applies to all
      subsequent copies and derivative works made from that copy.
       
      This option is useful when you wish to copy part of the code of
      the Library into a program that is not a library.
       
      4. You may copy and distribute the Library (or a portion or
      derivative of it, under Section 2) in object code or executable form
      under the terms of Sections 1 and 2 above provided that you accompany
      it with the complete corresponding machine-readable source code, which
      must be distributed under the terms of Sections 1 and 2 above on a
      medium customarily used for software interchange.
       
      If distribution of object code is made by offering access to copy
      from a designated place, then offering equivalent access to copy the
      source code from the same place satisfies the requirement to
      distribute the source code, even though third parties are not
      compelled to copy the source along with the object code.
       
      5. A program that contains no derivative of any portion of the
      Library, but is designed to work with the Library by being compiled or
      linked with it, is called a “work that uses the Library”. Such a
      work, in isolation, is not a derivative work of the Library, and
      therefore falls outside the scope of this License.
       
      However, linking a “work that uses the Library” with the Library
      creates an executable that is a derivative of the Library (because it
      contains portions of the Library), rather than a “work that uses the
      library”. The executable is therefore covered by this License.
      Section 6 states terms for distribution of such executables.
       
      When a “work that uses the Library” uses material from a header file
      that is part of the Library, the object code for the work may be a
      derivative work of the Library even though the source code is not.
      Whether this is true is especially significant if the work can be
      linked without the Library, or if the work is itself a library. The
      threshold for this to be true is not precisely defined by law.
       
      If such an object file uses only numerical parameters, data
      structure layouts and accessors, and small macros and small inline
      functions (ten lines or less in length), then the use of the object
      file is unrestricted, regardless of whether it is legally a derivative
      work. (Executables containing this object code plus portions of the
      Library will still fall under Section 6.)
       
      Otherwise, if the work is a derivative of the Library, you may
      distribute the object code for the work under the terms of Section 6.
      Any executables containing that work also fall under Section 6,
      whether or not they are linked directly with the Library itself.
       
      6. As an exception to the Sections above, you may also combine or
      link a “work that uses the Library” with the Library to produce a
      work containing portions of the Library, and distribute that work
      under terms of your choice, provided that the terms permit
      modification of the work for the customer’s own use and reverse
      engineering for debugging such modifications.
       
      You must give prominent notice with each copy of the work that the
      Library is used in it and that the Library and its use are covered by
      this License. You must supply a copy of this License. If the work
      during execution displays copyright notices, you must include the
      copyright notice for the Library among them, as well as a reference
      directing the user to the copy of this License. Also, you must do one
      of these things:
       
      a) Accompany the work with the complete corresponding
      machine-readable source code for the Library including whatever
      changes were used in the work (which must be distributed under
      Sections 1 and 2 above); and, if the work is an executable linked
      with the Library, with the complete machine-readable “work that
      uses the Library”, as object code and/or source code, so that the
      user can modify the Library and then relink to produce a modified
      executable containing the modified Library. (It is understood
      that the user who changes the contents of definitions files in the
      Library will not necessarily be able to recompile the application
      to use the modified definitions.)
       
      b) Use a suitable shared library mechanism for linking with the
      Library. A suitable mechanism is one that (1) uses at run time a
      copy of the library already present on the user’s computer system,
      rather than copying library functions into the executable, and (2)
      will operate properly with a modified version of the library, if
      the user installs one, as long as the modified version is
      interface-compatible with the version that the work was made with.
       
      c) Accompany the work with a written offer, valid for at
      least three years, to give the same user the materials
      specified in Subsection 6a, above, for a charge no more
      than the cost of performing this distribution.
       
      d) If distribution of the work is made by offering access to copy
      from a designated place, offer equivalent access to copy the above
      specified materials from the same place.
       
      e) Verify that the user has already received a copy of these
      materials or that you have already sent this user a copy.
       
      For an executable, the required form of the “work that uses the
      Library” must include any data and utility programs needed for
      reproducing the executable from it. However, as a special exception,
      the materials to be distributed need not include anything that is
      normally distributed (in either source or binary form) with the major
      components (compiler, kernel, and so on) of the operating system on
      which the executable runs, unless that component itself accompanies
      the executable.
       
      It may happen that this requirement contradicts the license
      restrictions of other proprietary libraries that do not normally
      accompany the operating system. Such a contradiction means you cannot
      use both them and the Library together in an executable that you
      distribute.
       
      7. You may place library facilities that are a work based on the
      Library side-by-side in a single library together with other library
      facilities not covered by this License, and distribute such a combined
      library, provided that the separate distribution of the work based on
      the Library and of the other library facilities is otherwise
      permitted, and provided that you do these two things:
       
      a) Accompany the combined library with a copy of the same work
      based on the Library, uncombined with any other library
      facilities. This must be distributed under the terms of the
      Sections above.
       
      b) Give prominent notice with the combined library of the fact
      that part of it is a work based on the Library, and explaining
      where to find the accompanying uncombined form of the same work.
       
      8. You may not copy, modify, sublicense, link with, or distribute
      the Library except as expressly provided under this License. Any
      attempt otherwise to copy, modify, sublicense, link with, or
      distribute the Library is void, and will automatically terminate your
      rights under this License. However, parties who have received copies,
      or rights, from you under this License will not have their licenses
      terminated so long as such parties remain in full compliance.
       
      9. You are not required to accept this License, since you have not
      signed it. However, nothing else grants you permission to modify or
      distribute the Library or its derivative works. These actions are
      prohibited by law if you do not accept this License. Therefore, by
      modifying or distributing the Library (or any work based on the
      Library), you indicate your acceptance of this License to do so, and
      all its terms and conditions for copying, distributing or modifying
      the Library or works based on it.
       
      10. Each time you redistribute the Library (or any work based on the
      Library), the recipient automatically receives a license from the
      original licensor to copy, distribute, link with or modify the Library
      subject to these terms and conditions. You may not impose any further
      restrictions on the recipients’ exercise of the rights granted herein.
      You are not responsible for enforcing compliance by third parties with
      this License.
       
      11. If, as a consequence of a court judgment or allegation of patent
      infringement or for any other reason (not limited to patent issues),
      conditions are imposed on you (whether by court order, agreement or
      otherwise) that contradict the conditions of this License, they do not
      excuse you from the conditions of this License. If you cannot
      distribute so as to satisfy simultaneously your obligations under this
      License and any other pertinent obligations, then as a consequence you
      may not distribute the Library at all. For example, if a patent
      license would not permit royalty-free redistribution of the Library by
      all those who receive copies directly or indirectly through you, then
      the only way you could satisfy both it and this License would be to
      refrain entirely from distribution of the Library.
       
      If any portion of this section is held invalid or unenforceable under any
      particular circumstance, the balance of the section is intended to apply,
      and the section as a whole is intended to apply in other circumstances.
       
      It is not the purpose of this section to induce you to infringe any
      patents or other property right claims or to contest validity of any
      such claims; this section has the sole purpose of protecting the
      integrity of the free software distribution system which is
      implemented by public license practices. Many people have made
      generous contributions to the wide range of software distributed
      through that system in reliance on consistent application of that
      system; it is up to the author/donor to decide if he or she is willing
      to distribute software through any other system and a licensee cannot
      impose that choice.
       
      This section is intended to make thoroughly clear what is believed to
      be a consequence of the rest of this License.
       
      12. If the distribution and/or use of the Library is restricted in
      certain countries either by patents or by copyrighted interfaces, the
      original copyright holder who places the Library under this License may add
      an explicit geographical distribution limitation excluding those countries,
      so that distribution is permitted only in or among countries not thus
      excluded. In such case, this License incorporates the limitation as if
      written in the body of this License.
       
      13. The Free Software Foundation may publish revised and/or new
      versions of the Lesser General Public License from time to time.
      Such new versions will be similar in spirit to the present version,
      but may differ in detail to address new problems or concerns.
       
      Each version is given a distinguishing version number. If the Library
      specifies a version number of this License which applies to it and
      “any later version”, you have the option of following the terms and
      conditions either of that version or of any later version published by
      the Free Software Foundation. If the Library does not specify a
      license version number, you may choose any version ever published by
      the Free Software Foundation.
       
      14. If you wish to incorporate parts of the Library into other free
      programs whose distribution conditions are incompatible with these,
      write to the author to ask for permission. For software which is
      copyrighted by the Free Software Foundation, write to the Free
      Software Foundation; we sometimes make exceptions for this. Our
      decision will be guided by the two goals of preserving the free status
      of all derivatives of our free software and of promoting the sharing
      and reuse of software generally.
       
      NO WARRANTY
       
      15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
      WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
      EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
      OTHER PARTIES PROVIDE THE LIBRARY “AS IS” WITHOUT WARRANTY OF ANY
      KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
      IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
      PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
      LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
      THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
       
      16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
      WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
      AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
      FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
      CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
      LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
      RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
      FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
      SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
      DAMAGES.

      GNU LESSER GENERAL PUBLIC LICENSE
      Version 3, 29 June 2007
       
      Copyright (C) 2007 Free Software Foundation, Inc. http://fsf.org/
      Everyone is permitted to copy and distribute verbatim copies
      of this license document, but changing it is not allowed.
       
      This version of the GNU Lesser General Public License incorporates
      the terms and conditions of version 3 of the GNU General Public
      License, supplemented by the additional permissions listed below.
       
      0. Additional Definitions.
       
      As used herein, “this License” refers to version 3 of the GNU Lesser
      General Public License, and the “GNU GPL” refers to version 3 of the GNU
      General Public License.
       
      “The Library” refers to a covered work governed by this License,
      other than an Application or a Combined Work as defined below.
       
      An “Application” is any work that makes use of an interface provided
      by the Library, but which is not otherwise based on the Library.
      Defining a subclass of a class defined by the Library is deemed a mode
      of using an interface provided by the Library.
       
      A “Combined Work” is a work produced by combining or linking an
      Application with the Library. The particular version of the Library
      with which the Combined Work was made is also called the “Linked
      Version”.
       
      The “Minimal Corresponding Source” for a Combined Work means the
      Corresponding Source for the Combined Work, excluding any source code
      for portions of the Combined Work that, considered in isolation, are
      based on the Application, and not on the Linked Version.
       
      The “Corresponding Application Code” for a Combined Work means the
      object code and/or source code for the Application, including any data
      and utility programs needed for reproducing the Combined Work from the
      Application, but excluding the System Libraries of the Combined Work.
       
      1. Exception to Section 3 of the GNU GPL.
       
      You may convey a covered work under sections 3 and 4 of this License
      without being bound by section 3 of the GNU GPL.
       
      2. Conveying Modified Versions.
       
      If you modify a copy of the Library, and, in your modifications, a
      facility refers to a function or data to be supplied by an Application
      that uses the facility (other than as an argument passed when the
      facility is invoked), then you may convey a copy of the modified
      version:
       
      a) under this License, provided that you make a good faith effort to
      ensure that, in the event an Application does not supply the
      function or data, the facility still operates, and performs
      whatever part of its purpose remains meaningful, or
       
      b) under the GNU GPL, with none of the additional permissions of
      this License applicable to that copy.
       
      3. Object Code Incorporating Material from Library Header Files.
       
      The object code form of an Application may incorporate material from
      a header file that is part of the Library. You may convey such object
      code under terms of your choice, provided that, if the incorporated
      material is not limited to numerical parameters, data structure
      layouts and accessors, or small macros, inline functions and templates
      (ten or fewer lines in length), you do both of the following:
       
      a) Give prominent notice with each copy of the object code that the
      Library is used in it and that the Library and its use are
      covered by this License.
       
      b) Accompany the object code with a copy of the GNU GPL and this license
      document.
       
      4. Combined Works.
       
      You may convey a Combined Work under terms of your choice that,
      taken together, effectively do not restrict modification of the
      portions of the Library contained in the Combined Work and reverse
      engineering for debugging such modifications, if you also do each of
      the following:
       
      a) Give prominent notice with each copy of the Combined Work that
      the Library is used in it and that the Library and its use are
      covered by this License.
       
      b) Accompany the Combined Work with a copy of the GNU GPL and this license
      document.
       
      c) For a Combined Work that displays copyright notices during
      execution, include the copyright notice for the Library among
      these notices, as well as a reference directing the user to the
      copies of the GNU GPL and this license document.
       
      d) Do one of the following:
       
      0) Convey the Minimal Corresponding Source under the terms of this
      License, and the Corresponding Application Code in a form
      suitable for, and under terms that permit, the user to
      recombine or relink the Application with a modified version of
      the Linked Version to produce a modified Combined Work, in the
      manner specified by section 6 of the GNU GPL for conveying
      Corresponding Source.
       
      1) Use a suitable shared library mechanism for linking with the
      Library. A suitable mechanism is one that (a) uses at run time
      a copy of the Library already present on the user’s computer
      system, and (b) will operate properly with a modified version
      of the Library that is interface-compatible with the Linked
      Version.
       
      e) Provide Installation Information, but only if you would otherwise
      be required to provide such information under section 6 of the
      GNU GPL, and only to the extent that such information is
      necessary to install and execute a modified version of the
      Combined Work produced by recombining or relinking the
      Application with a modified version of the Linked Version. (If
      you use option 4d0, the Installation Information must accompany
      the Minimal Corresponding Source and Corresponding Application
      Code. If you use option 4d1, you must provide the Installation
      Information in the manner specified by section 6 of the GNU GPL
      for conveying Corresponding Source.)
       
      5. Combined Libraries.
       
      You may place library facilities that are a work based on the
      Library side by side in a single library together with other library
      facilities that are not Applications and are not covered by this
      License, and convey such a combined library under terms of your
      choice, if you do both of the following:
       
      a) Accompany the combined library with a copy of the same work based
      on the Library, uncombined with any other library facilities,
      conveyed under the terms of this License.
       
      b) Give prominent notice with the combined library that part of it
      is a work based on the Library, and explaining where to find the
      accompanying uncombined form of the same work.
       
      6. Revised Versions of the GNU Lesser General Public License.
       
      The Free Software Foundation may publish revised and/or new versions
      of the GNU Lesser General Public License from time to time. Such new
      versions will be similar in spirit to the present version, but may
      differ in detail to address new problems or concerns.
       
      Each version is given a distinguishing version number. If the
      Library as you received it specifies that a certain numbered version
      of the GNU Lesser General Public License “or any later version”
      applies to it, you have the option of following the terms and
      conditions either of that published version or of any later version
      published by the Free Software Foundation. If the Library as you
      received it does not specify a version number of the GNU Lesser
      General Public License, you may choose any version of the GNU Lesser
      General Public License ever published by the Free Software Foundation.
       
      If the Library as you received it specifies that a proxy can decide
      whether future versions of the GNU Lesser General Public License shall
      apply, that proxy’s public statement of acceptance of any version is
      permanent authorization for you to choose that version for the
      Library.

      The FreeType Project LICENSE
       
      2006-Jan-27
       
      Copyright 1996-2002, 2006 by
      David Turner, Robert Wilhelm, and Werner Lemberg
       
       
       
      Introduction
       
      The FreeType Project is distributed in several archive packages;
      some of them may contain, in addition to the FreeType font engine,
      various tools and contributions which rely on, or relate to, the
      FreeType Project.
       
      This license applies to all files found in such packages, and
      which do not fall under their own explicit license. The license
      affects thus the FreeType font engine, the test programs,
      documentation and makefiles, at the very least.
       
      This license was inspired by the BSD, Artistic, and IJG
      (Independent JPEG Group) licenses, which all encourage inclusion
      and use of free software in commercial and freeware products
      alike. As a consequence, its main points are that:
       
      o We don’t promise that this software works. However, we will be
      interested in any kind of bug reports. (`as is’ distribution)
       
      o You can use this software for whatever you want, in parts or
      full form, without having to pay us. (`royalty-free’ usage)
       
      o You may not pretend that you wrote this software. If you use
      it, or only parts of it, in a program, you must acknowledge
      somewhere in your documentation that you have used the
      FreeType code. (`credits’)
       
      We specifically permit and encourage the inclusion of this
      software, with or without modifications, in commercial products.
      We disclaim all warranties covering The FreeType Project and
      assume no liability related to The FreeType Project.
       
       
      Finally, many people asked us for a preferred form for a
      credit/disclaimer to use in compliance with this license. We thus
      encourage you to use the following text:
       
      ”””
      Portions of this software are copyright © The FreeType
      Project (www.freetype.org). All rights reserved.
      ”””
       
      Please replace with the value from the FreeType version you
      actually use.
       
       
      Legal Terms
       
      0. Definitions
       
      Throughout this license, the terms package', FreeType Project’,
      and `FreeType archive’ refer to the set of files originally
      distributed by the authors (David Turner, Robert Wilhelm, and
      Werner Lemberg) as the `FreeType Project’, be they named as alpha,
      beta or final release.
       
      `You’ refers to the licensee, or person using the project, where
      `using’ is a generic term including compiling the project’s source
      code as well as linking it to form a program' or executable’.
      This program is referred to as `a program using the FreeType
      engine’.
       
      This license applies to all files distributed in the original
      FreeType Project, including all source code, binaries and
      documentation, unless otherwise stated in the file in its
      original, unmodified form as distributed in the original archive.
      If you are unsure whether or not a particular file is covered by
      this license, you must contact us to verify this.
       
      The FreeType Project is copyright (C) 1996-2000 by David Turner,
      Robert Wilhelm, and Werner Lemberg. All rights reserved except as
      specified below.
       
      1. No Warranty
       
      THE FREETYPE PROJECT IS PROVIDED `AS IS’ WITHOUT WARRANTY OF ANY
      KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
      WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
      PURPOSE. IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
      BE LIABLE FOR ANY DAMAGES CAUSED BY THE USE OR THE INABILITY TO
      USE, OF THE FREETYPE PROJECT.
       
      2. Redistribution
       
      This license grants a worldwide, royalty-free, perpetual and
      irrevocable right and license to use, execute, perform, compile,
      display, copy, create derivative works of, distribute and
      sublicense the FreeType Project (in both source and object code
      forms) and derivative works thereof for any purpose; and to
      authorize others to exercise some or all of the rights granted
      herein, subject to the following conditions:
       
      o Redistribution of source code must retain this license file
      (`FTL.TXT’) unaltered; any additions, deletions or changes to
      the original files must be clearly indicated in accompanying
      documentation. The copyright notices of the unaltered,
      original files must be preserved in all copies of source
      files.
       
      o Redistribution in binary form must provide a disclaimer that
      states that the software is based in part of the work of the
      FreeType Team, in the distribution documentation. We also
      encourage you to put an URL to the FreeType web page in your
      documentation, though this isn’t mandatory.
       
      These conditions apply to any software derived from or based on
      the FreeType Project, not just the unmodified files. If you use
      our work, you must acknowledge us. However, no fee need be paid
      to us.
       
      3. Advertising
       
      Neither the FreeType authors and contributors nor you shall use
      the name of the other for commercial, advertising, or promotional
      purposes without specific prior written permission.
       
      We suggest, but do not require, that you use one or more of the
      following phrases to refer to this software in your documentation
      or advertising materials: FreeType Project', FreeType Engine’,
      FreeType library', or FreeType Distribution’.
       
      As you have not signed this license, you are not required to
      accept it. However, as the FreeType Project is copyrighted
      material, only this license, or another one contracted with the
      authors, grants you the right to use, distribute, and modify it.
      Therefore, by using, distributing, or modifying the FreeType
      Project, you indicate that you understand and accept all the terms
      of this license.
       
      4. Contacts
       
      There are two mailing lists related to FreeType:
       
      o freetype@nongnu.org
       
      Discusses general use and applications of FreeType, as well as
      future and wanted additions to the library and distribution.
      If you are looking for support, start in this list if you
      haven’t found anything to help you in the documentation.
       
      o freetype-devel@nongnu.org
       
      Discusses bugs, as well as engine internals, design issues,
      specific licenses, porting, etc.

      2. License Grants and Conditions
       
      2.1. Grants
       
      Each Contributor hereby grants You a world-wide, royalty-free,
      non-exclusive license:
       
      (a) under intellectual property rights (other than patent or trademark)
      Licensable by such Contributor to use, reproduce, make available,
      modify, display, perform, distribute, and otherwise exploit its
      Contributions, either on an unmodified basis, with Modifications, or
      as part of a Larger Work; and
       
      (b) under Patent Claims of such Contributor to make, use, sell, offer
      for sale, have made, import, and otherwise transfer either its
      Contributions or its Contributor Version.
       
      2.2. Effective Date
       
      The licenses granted in Section 2.1 with respect to any Contribution
      become effective for each Contribution on the date the Contributor first
      distributes such Contribution.
       
      2.3. Limitations on Grant Scope
       
      The licenses granted in this Section 2 are the only rights granted under
      this License. No additional rights or licenses will be implied from the
      distribution or licensing of Covered Software under this License.
      Notwithstanding Section 2.1(b) above, no patent license is granted by a
      Contributor:
       
      (a) for any code that a Contributor has removed from Covered Software;
      or
       
      (b) for infringements caused by: (i) Your and any other third party’s
      modifications of Covered Software, or (ii) the combination of its
      Contributions with other software (except as part of its Contributor
      Version); or
       
      (c) under Patent Claims infringed by Covered Software in the absence of
      its Contributions.
       
      This License does not grant any rights in the trademarks, service marks,
      or logos of any Contributor (except as may be necessary to comply with
      the notice requirements in Section 3.4).
       
      2.4. Subsequent Licenses
       
      No Contributor makes additional grants as a result of Your choice to
      distribute the Covered Software under a subsequent version of this
      License (see Section 10.2) or under the terms of a Secondary License (if
      permitted under the terms of Section 3.3).
       
      2.5. Representation
       
      Each Contributor represents that the Contributor believes its
      Contributions are its original creation(s) or it has sufficient rights
      to grant the rights to its Contributions conveyed by this License.
       
      2.6. Fair Use
       
      This License is not intended to limit any rights You have under
      applicable copyright doctrines of fair use, fair dealing, or other
      equivalents.
       
      2.7. Conditions
       
      Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
      in Section 2.1.
       
      3. Responsibilities
       
      3.1. Distribution of Source Form
       
      All distribution of Covered Software in Source Code Form, including any
      Modifications that You create or to which You contribute, must be under
      the terms of this License. You must inform recipients that the Source
      Code Form of the Covered Software is governed by the terms of this
      License, and how they can obtain a copy of this License. You may not
      attempt to alter or restrict the recipients’ rights in the Source Code
      Form.
       
      3.2. Distribution of Executable Form
       
      If You distribute Covered Software in Executable Form then:
       
      (a) such Covered Software must also be made available in Source Code
      Form, as described in Section 3.1, and You must inform recipients of
      the Executable Form how they can obtain a copy of such Source Code
      Form by reasonable means in a timely manner, at a charge no more
      than the cost of distribution to the recipient; and
       
      (b) You may distribute such Executable Form under the terms of this
      License, or sublicense it under different terms, provided that the
      license for the Executable Form does not attempt to limit or alter
      the recipients’ rights in the Source Code Form under this License.
       
      3.3. Distribution of a Larger Work
       
      You may create and distribute a Larger Work under terms of Your choice,
      provided that You also comply with the requirements of this License for
      the Covered Software. If the Larger Work is a combination of Covered
      Software with a work governed by one or more Secondary Licenses, and the
      Covered Software is not Incompatible With Secondary Licenses, this
      License permits You to additionally distribute such Covered Software
      under the terms of such Secondary License(s), so that the recipient of
      the Larger Work may, at their option, further distribute the Covered
      Software under the terms of either this License or such Secondary
      License(s).
       
      3.4. Notices
       
      You may not remove or alter the substance of any license notices
      (including copyright notices, patent notices, disclaimers of warranty,
      or limitations of liability) contained within the Source Code Form of
      the Covered Software, except that You may alter any license notices to
      the extent required to remedy known factual inaccuracies.
       
      3.5. Application of Additional Terms
       
      You may choose to offer, and to charge a fee for, warranty, support,
      indemnity or liability obligations to one or more recipients of Covered
      Software. However, You may do so only on Your own behalf, and not on
      behalf of any Contributor. You must make it absolutely clear that any
      such warranty, support, indemnity, or liability obligation is offered by
      You alone, and You hereby agree to indemnify every Contributor for any
      liability incurred by such Contributor as a result of warranty, support,
      indemnity or liability terms You offer. You may include additional
      disclaimers of warranty and limitations of liability specific to any
      jurisdiction.
       
      4. Inability to Comply Due to Statute or Regulation
       
      If it is impossible for You to comply with any of the terms of this
      License with respect to some or all of the Covered Software due to
      statute, judicial order, or regulation then You must: (a) comply with
      the terms of this License to the maximum extent possible; and (b)
      describe the limitations and the code they affect. Such description must
      be placed in a text file included with all distributions of the Covered
      Software under this License. Except to the extent prohibited by statute
      or regulation, such description must be sufficiently detailed for a
      recipient of ordinary skill to be able to understand it.
       
      5. Termination
       
      5.1. The rights granted under this License will terminate automatically
      if You fail to comply with any of its terms. However, if You become
      compliant, then the rights granted under this License from a particular
      Contributor are reinstated (a) provisionally, unless and until such
      Contributor explicitly and finally terminates Your grants, and (b) on an
      ongoing basis, if such Contributor fails to notify You of the
      non-compliance by some reasonable means prior to 60 days after You have
      come back into compliance. Moreover, Your grants from a particular
      Contributor are reinstated on an ongoing basis if such Contributor
      notifies You of the non-compliance by some reasonable means, this is the
      first time You have received notice of non-compliance with this License
      from such Contributor, and You become compliant prior to 30 days after
      Your receipt of the notice.
       
      5.2. If You initiate litigation against any entity by asserting a patent
      infringement claim (excluding declaratory judgment actions,
      counter-claims, and cross-claims) alleging that a Contributor Version
      directly or indirectly infringes any patent, then the rights granted to
      You by any and all Contributors for the Covered Software under Section
      2.1 of this License shall terminate.
       
      5.3. In the event of termination under Sections 5.1 or 5.2 above, all
      end user license agreements (excluding distributors and resellers) which
      have been validly granted by You or Your distributors under this License
      prior to termination shall survive termination.
       
      ************************
      * *
      * 6. Disclaimer of Warranty *
      * ————————- *
      * *
      * Covered Software is provided under this License on an “as is” *
      * basis, without warranty of any kind, either expressed, implied, or *
      * statutory, including, without limitation, warranties that the *
      * Covered Software is free of defects, merchantable, fit for a *
      * particular purpose or non-infringing. The entire risk as to the *
      * quality and performance of the Covered Software is with You. *
      * Should any Covered Software prove defective in any respect, You *
      * (not any Contributor) assume the cost of any necessary servicing, *
      * repair, or correction. This disclaimer of warranty constitutes an *
      * essential part of this License. No use of any Covered Software is *
      * authorized under this License except under this disclaimer. *
      * *
      ************************
       
      ************************
      * *
      * 7. Limitation of Liability *
      * ————————– *
      * *
      * Under no circumstances and under no legal theory, whether tort *
      * (including negligence), contract, or otherwise, shall any *
      * Contributor, or anyone who distributes Covered Software as *
      * permitted above, be liable to You for any direct, indirect, *
      * special, incidental, or consequential damages of any character *
      * including, without limitation, damages for lost profits, loss of *
      * goodwill, work stoppage, computer failure or malfunction, or any *
      * and all other commercial damages or losses, even if such party *
      * shall have been informed of the possibility of such damages. This *
      * limitation of liability shall not apply to liability for death or *
      * personal injury resulting from such party’s negligence to the *
      * extent applicable law prohibits such limitation. Some *
      * jurisdictions do not allow the exclusion or limitation of *
      * incidental or consequential damages, so this exclusion and *
      * limitation may not apply to You. *
      * *
      ************************
       
      8. Litigation
       
      Any litigation relating to this License may be brought only in the
      courts of a jurisdiction where the defendant maintains its principal
      place of business and such litigation shall be governed by laws of that
      jurisdiction, without reference to its conflict-of-law provisions.
      Nothing in this Section shall prevent a party’s ability to bring
      cross-claims or counter-claims.
       
      9. Miscellaneous
       
      This License represents the complete agreement concerning the subject
      matter hereof. If any provision of this License is held to be
      unenforceable, such provision shall be reformed only to the extent
      necessary to make it enforceable. Any law or regulation which provides
      that the language of a contract shall be construed against the drafter
      shall not be used to construe this License against a Contributor.
       
      10. Versions of the License
       
      10.1. New Versions
       
      Mozilla Foundation is the license steward. Except as provided in Section
      10.3, no one other than the license steward has the right to modify or
      publish new versions of this License. Each version will be given a
      distinguishing version number.
       
      10.2. Effect of New Versions
       
      You may distribute the Covered Software under the terms of the version
      of the License under which You originally received the Covered Software,
      or under the terms of any subsequent version published by the license
      steward.
       
      10.3. Modified Versions
       
      If you create software not governed by this License, and you want to
      create a new license for such software, you may create and use a
      modified version of this License if you rename the license and remove
      any references to the name of the license steward (except to note that
      such modified license differs from this License).
       
      10.4. Distributing Source Code Form that is Incompatible With Secondary
      Licenses
       
      If You choose to distribute Source Code Form that is Incompatible With
      Secondary Licenses under the terms of this version of the License, the
      notice described in Exhibit B of this License must be attached.
       
      Exhibit A - Source Code Form License Notice

      License, v. 2.0. If a copy of the MPL was not distributed with this

      If it is not possible or desirable to put the notice in a particular
      file, then You may include the notice in a location (such as a LICENSE
      file in a relevant directory) where a recipient would be likely to look
      for such a notice.
       
      You may add additional accurate notices of copyright ownership.

      Libjpeg-turbo is redistributed within all opencv-python packages as build option.
       
      libjpeg-turbo Licenses
       
      libjpeg-turbo is covered by three compatible BSD-style open source licenses:
       
      - The IJG (Independent JPEG Group) License, which is listed in
      README.ijg
       
      This license applies to the libjpeg API library and associated programs
      (any code inherited from libjpeg, and any modifications to that code.)
       
      - The Modified (3-clause) BSD License, which is listed below
       
      This license covers the TurboJPEG API library and associated programs, as
      well as the build system.
       
      - The zlib License
       
      This license is a subset of the other two, and it covers the libjpeg-turbo
      SIMD extensions.
       
       
      Complying with the libjpeg-turbo Licenses
       
      This section provides a roll-up of the libjpeg-turbo licensing terms, to the
      best of our understanding.
       
      1. If you are distributing a modified version of the libjpeg-turbo source,
      then:
       
      1. You cannot alter or remove any existing copyright or license notices
      from the source.
       
      Origin
      - Clause 1 of the IJG License
      - Clause 1 of the Modified BSD License
      - Clauses 1 and 3 of the zlib License
       
      2. You must add your own copyright notice to the header of each source
      file you modified, so others can tell that you modified that file (if
      there is not an existing copyright header in that file, then you can
      simply add a notice stating that you modified the file.)
       
      Origin
      - Clause 1 of the IJG License
      - Clause 2 of the zlib License
       
      3. You must include the IJG README file, and you must not alter any of the
      copyright or license text in that file.
       
      Origin
      - Clause 1 of the IJG License
       
      2. If you are distributing only libjpeg-turbo binaries without the source, or
      if you are distributing an application that statically links with
      libjpeg-turbo, then:
       
      1. Your product documentation must include a message stating:
       
      This software is based in part on the work of the Independent JPEG
      Group.
       
      Origin
      - Clause 2 of the IJG license
       
      2. If your binary distribution includes or uses the TurboJPEG API, then
      your product documentation must include the text of the Modified BSD
      License (see below.)
       
      Origin
      - Clause 2 of the Modified BSD License
       
      3. You cannot use the name of the IJG or The libjpeg-turbo Project or the
      contributors thereof in advertising, publicity, etc.
       
      Origin
      - IJG License
      - Clause 3 of the Modified BSD License
       
      4. The IJG and The libjpeg-turbo Project do not warrant libjpeg-turbo to be
      free of defects, nor do we accept any liability for undesirable
      consequences resulting from your use of the software.
       
      Origin
      - IJG License
      - Modified BSD License
      - zlib License

      ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE
      POSSIBILITY OF SUCH DAMAGE.
       
       
      Why Three Licenses?
       
      The zlib License could have been used instead of the Modified (3-clause) BSD
      License, and since the IJG License effectively subsumes the distribution
      conditions of the zlib License, this would have effectively placed
      libjpeg-turbo binary distributions under the IJG License. However, the IJG
      License specifically refers to the Independent JPEG Group and does not extend
      attribution and endorsement protections to other entities. Thus, it was
      desirable to choose a license that granted us the same protections for new code
      that were granted to the IJG for code derived from their software.

      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).
       
      “Derivative Works” shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications

      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work

      attribution notices from the Source form of the Work,
      excluding those notices that do not pertain to any part of
      the Derivative Works; and
       
      (d) If the Work includes a “NOTICE” text file as part of its
      distribution, then any Derivative Works that You distribute must
      include a readable copy of the attribution notices contained
      within such NOTICE file, excluding those notices that do not
      pertain to any part of the Derivative Works, in at least one
      of the following places: within a NOTICE text file distributed
      as part of the Derivative Works; within the Source form or
      documentation, if provided along with the Derivative Works; or,
      within a display generated by the Derivative Works, if and
      wherever such third-party notices normally appear. The contents
      of the NOTICE file are for informational purposes only and
      do not modify the License. You may add Your own attribution
      notices within Derivative Works that You distribute, alongside
      or as an addendum to the NOTICE text from the Work, provided
      that such additional attribution notices cannot be construed
      as modifying the License.
       
      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.
       
      5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.
       
      6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.
       
      7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an “AS IS” BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.
       
      8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.
       
      9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

      FREETYPE LICENSES
       
      The FreeType 2 font engine is copyrighted work and cannot be used
      legally without a software license. In order to make this project
      usable to a vast majority of developers, we distribute it under two
      mutually exclusive open-source licenses.
       
      This means that you must choose one of the two licenses described
      below, then obey all its terms and conditions when using FreeType 2 in
      any of your projects or products.
       
      - The FreeType License, found in the file docs/FTL.TXT, which is
      similar to the original BSD license with an advertising clause
      that forces you to explicitly cite the FreeType project in your
      product’s documentation. All details are in the license file.
      This license is suited to products which don’t use the GNU General
      Public License.
       
      Note that this license is compatible to the GNU General Public
      License version 3, but not version 2.
       
      - The GNU General Public License version 2, found in
      docs/GPLv2.TXT (any later version can be used also), for
      programs which already use the GPL. Note that the FTL is
      incompatible with GPLv2 due to its advertisement clause.
       
      The contributed BDF and PCF drivers come with a license similar to
      that of the X Window System. It is compatible to the above two
      licenses (see files src/bdf/README and src/pcf/README). The same
      holds for the source code files src/base/fthash.c and
      include/freetype/internal/fthash.h; they were part of the BDF driver
      in earlier FreeType versions.
       
      The gzip module uses the zlib license (see src/gzip/zlib.h) which
      too is compatible to the above two licenses.
       
      The files src/autofit/ft-hb.c and src/autofit/ft-hb.h contain code
      taken almost verbatim from the HarfBuzz file hb-ft.cc, which uses
      the ‘Old MIT’ license, compatible to the above two licenses.
       
      The MD5 checksum support (only used for debugging in development
      builds) is in the public domain.

      Copyright 1996-2002, 2006 by
      David Turner, Robert Wilhelm, and Werner Lemberg
       
       
       
      Introduction
       
      The FreeType Project is distributed in several archive packages;
      some of them may contain, in addition to the FreeType font engine,
      various tools and contributions which rely on, or relate to, the
      FreeType Project.
       
      This license applies to all files found in such packages, and
      which do not fall under their own explicit license. The license
      affects thus the FreeType font engine, the test programs,
      documentation and makefiles, at the very least.
       
      This license was inspired by the BSD, Artistic, and IJG
      (Independent JPEG Group) licenses, which all encourage inclusion
      and use of free software in commercial and freeware products
      alike. As a consequence, its main points are that:
       
      o We don’t promise that this software works. However, we will be
      interested in any kind of bug reports. (`as is’ distribution)
       
      o You can use this software for whatever you want, in parts or
      full form, without having to pay us. (`royalty-free’ usage)
       
      o You may not pretend that you wrote this software. If you use
      it, or only parts of it, in a program, you must acknowledge
      somewhere in your documentation that you have used the
      FreeType code. (`credits’)
       
      We specifically permit and encourage the inclusion of this
      software, with or without modifications, in commercial products.
      We disclaim all warranties covering The FreeType Project and
      assume no liability related to The FreeType Project.
       
       
      Finally, many people asked us for a preferred form for a
      credit/disclaimer to use in compliance with this license. We thus
      encourage you to use the following text:
       
      ”””
      Portions of this software are copyright © The FreeType
      Project (www.freetype.org). All rights reserved.
      ”””
       
      Please replace with the value from the FreeType version you
      actually use.
       
       
      Legal Terms
       
      0. Definitions
       
      Throughout this license, the terms package', FreeType Project’,
      and `FreeType archive’ refer to the set of files originally
      distributed by the authors (David Turner, Robert Wilhelm, and
      Werner Lemberg) as the `FreeType Project’, be they named as alpha,
      beta or final release.
       
      `You’ refers to the licensee, or person using the project, where
      `using’ is a generic term including compiling the project’s source
      code as well as linking it to form a program' or executable’.
      This program is referred to as `a program using the FreeType
      engine’.
       
      This license applies to all files distributed in the original
      FreeType Project, including all source code, binaries and
      documentation, unless otherwise stated in the file in its
      original, unmodified form as distributed in the original archive.
      If you are unsure whether or not a particular file is covered by
      this license, you must contact us to verify this.
       
      The FreeType Project is copyright (C) 1996-2000 by David Turner,
      Robert Wilhelm, and Werner Lemberg. All rights reserved except as
      specified below.
       
      1. No Warranty
       
      THE FREETYPE PROJECT IS PROVIDED `AS IS’ WITHOUT WARRANTY OF ANY
      KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
      WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
      PURPOSE. IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
      BE LIABLE FOR ANY DAMAGES CAUSED BY THE USE OR THE INABILITY TO
      USE, OF THE FREETYPE PROJECT.
       
      2. Redistribution
       
      This license grants a worldwide, royalty-free, perpetual and
      irrevocable right and license to use, execute, perform, compile,
      display, copy, create derivative works of, distribute and
      sublicense the FreeType Project (in both source and object code
      forms) and derivative works thereof for any purpose; and to
      authorize others to exercise some or all of the rights granted
      herein, subject to the following conditions:
       
      o Redistribution of source code must retain this license file
      (`FTL.TXT’) unaltered; any additions, deletions or changes to
      the original files must be clearly indicated in accompanying
      documentation. The copyright notices of the unaltered,
      original files must be preserved in all copies of source
      files.
       
      o Redistribution in binary form must provide a disclaimer that
      states that the software is based in part of the work of the
      FreeType Team, in the distribution documentation. We also
      encourage you to put an URL to the FreeType web page in your
      documentation, though this isn’t mandatory.
       
      These conditions apply to any software derived from or based on
      the FreeType Project, not just the unmodified files. If you use
      our work, you must acknowledge us. However, no fee need be paid
      to us.
       
      3. Advertising
       
      Neither the FreeType authors and contributors nor you shall use
      the name of the other for commercial, advertising, or promotional
      purposes without specific prior written permission.
       
      We suggest, but do not require, that you use one or more of the
      following phrases to refer to this software in your documentation
      or advertising materials: FreeType Project', FreeType Engine’,
      FreeType library', or FreeType Distribution’.
       
      As you have not signed this license, you are not required to
      accept it. However, as the FreeType Project is copyrighted
      material, only this license, or another one contracted with the
      authors, grants you the right to use, distribute, and modify it.
      Therefore, by using, distributing, or modifying the FreeType
      Project, you indicate that you understand and accept all the terms
      of this license.

      GNU GENERAL PUBLIC LICENSE
      Version 2, June 1991
       
      Copyright (C) 1989, 1991 Free Software Foundation, Inc.
      51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
      Everyone is permitted to copy and distribute verbatim copies
      of this license document, but changing it is not allowed.
       
      Preamble
       
      The licenses for most software are designed to take away your
      freedom to share and change it. By contrast, the GNU General Public
      License is intended to guarantee your freedom to share and change free
      software–to make sure the software is free for all its users. This
      General Public License applies to most of the Free Software
      Foundation’s software and to any other program whose authors commit to
      using it. (Some other Free Software Foundation software is covered by
      the GNU Library General Public License instead.) You can apply it to
      your programs, too.
       
      When we speak of free software, we are referring to freedom, not
      price. Our General Public Licenses are designed to make sure that you
      have the freedom to distribute copies of free software (and charge for
      this service if you wish), that you receive source code or can get it
      if you want it, that you can change the software or use pieces of it
      in new free programs; and that you know you can do these things.
       
      To protect your rights, we need to make restrictions that forbid
      anyone to deny you these rights or to ask you to surrender the rights.
      These restrictions translate to certain responsibilities for you if you
      distribute copies of the software, or if you modify it.
       
      For example, if you distribute copies of such a program, whether
      gratis or for a fee, you must give the recipients all the rights that
      you have. You must make sure that they, too, receive or can get the
      source code. And you must show them these terms so they know their
      rights.
       
      We protect your rights with two steps: (1) copyright the software, and
      (2) offer you this license which gives you legal permission to copy,
      distribute and/or modify the software.
       
      Also, for each author’s protection and ours, we want to make certain
      that everyone understands that there is no warranty for this free
      software. If the software is modified by someone else and passed on, we
      want its recipients to know that what they have is not the original, so
      that any problems introduced by others will not reflect on the original
      authors’ reputations.
       
      Finally, any free program is threatened constantly by software
      patents. We wish to avoid the danger that redistributors of a free
      program will individually obtain patent licenses, in effect making the
      program proprietary. To prevent this, we have made it clear that any
      patent must be licensed for everyone’s free use or not licensed at all.
       
      The precise terms and conditions for copying, distribution and
      modification follow.
       
      GNU GENERAL PUBLIC LICENSE
      TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
       
      0. This License applies to any program or other work which contains
      a notice placed by the copyright holder saying it may be distributed
      under the terms of this General Public License. The “Program”, below,
      refers to any such program or work, and a “work based on the Program”
      means either the Program or any derivative work under copyright law:
      that is to say, a work containing the Program or a portion of it,
      either verbatim or with modifications and/or translated into another
      language. (Hereinafter, translation is included without limitation in
      the term “modification”.) Each licensee is addressed as “you”.
       
      Activities other than copying, distribution and modification are not
      covered by this License; they are outside its scope. The act of
      running the Program is not restricted, and the output from the Program
      is covered only if its contents constitute a work based on the
      Program (independent of having been made by running the Program).
      Whether that is true depends on what the Program does.
       
      1. You may copy and distribute verbatim copies of the Program’s
      source code as you receive it, in any medium, provided that you
      conspicuously and appropriately publish on each copy an appropriate
      copyright notice and disclaimer of warranty; keep intact all the
      notices that refer to this License and to the absence of any warranty;
      and give any other recipients of the Program a copy of this License
      along with the Program.
       
      You may charge a fee for the physical act of transferring a copy, and
      you may at your option offer warranty protection in exchange for a fee.
       
      2. You may modify your copy or copies of the Program or any portion
      of it, thus forming a work based on the Program, and copy and
      distribute such modifications or work under the terms of Section 1
      above, provided that you also meet all of these conditions:
       
      a) You must cause the modified files to carry prominent notices
      stating that you changed the files and the date of any change.
       
      b) You must cause any work that you distribute or publish, that in
      whole or in part contains or is derived from the Program or any
      part thereof, to be licensed as a whole at no charge to all third
      parties under the terms of this License.
       
      c) If the modified program normally reads commands interactively
      when run, you must cause it, when started running for such
      interactive use in the most ordinary way, to print or display an
      announcement including an appropriate copyright notice and a
      notice that there is no warranty (or else, saying that you provide
      a warranty) and that users may redistribute the program under
      these conditions, and telling the user how to view a copy of this
      License. (Exception: if the Program itself is interactive but
      does not normally print such an announcement, your work based on
      the Program is not required to print an announcement.)
       
      These requirements apply to the modified work as a whole. If
      identifiable sections of that work are not derived from the Program,
      and can be reasonably considered independent and separate works in
      themselves, then this License, and its terms, do not apply to those
      sections when you distribute them as separate works. But when you
      distribute the same sections as part of a whole which is a work based
      on the Program, the distribution of the whole must be on the terms of
      this License, whose permissions for other licensees extend to the
      entire whole, and thus to each and every part regardless of who wrote it.
       
      Thus, it is not the intent of this section to claim rights or contest
      your rights to work written entirely by you; rather, the intent is to
      exercise the right to control the distribution of derivative or
      collective works based on the Program.
       
      In addition, mere aggregation of another work not based on the Program
      with the Program (or with a work based on the Program) on a volume of
      a storage or distribution medium does not bring the other work under
      the scope of this License.
       
      3. You may copy and distribute the Program (or a work based on it,
      under Section 2) in object code or executable form under the terms of
      Sections 1 and 2 above provided that you also do one of the following:
       
      a) Accompany it with the complete corresponding machine-readable
      source code, which must be distributed under the terms of Sections
      1 and 2 above on a medium customarily used for software interchange; or,
       
      b) Accompany it with a written offer, valid for at least three
      years, to give any third party, for a charge no more than your
      cost of physically performing source distribution, a complete
      machine-readable copy of the corresponding source code, to be
      distributed under the terms of Sections 1 and 2 above on a medium
      customarily used for software interchange; or,
       
      c) Accompany it with the information you received as to the offer
      to distribute corresponding source code. (This alternative is
      allowed only for noncommercial distribution and only if you
      received the program in object code or executable form with such
      an offer, in accord with Subsection b above.)
       
      The source code for a work means the preferred form of the work for
      making modifications to it. For an executable work, complete source
      code means all the source code for all modules it contains, plus any
      associated interface definition files, plus the scripts used to
      control compilation and installation of the executable. However, as a
      special exception, the source code distributed need not include
      anything that is normally distributed (in either source or binary
      form) with the major components (compiler, kernel, and so on) of the
      operating system on which the executable runs, unless that component
      itself accompanies the executable.
       
      If distribution of executable or object code is made by offering
      access to copy from a designated place, then offering equivalent
      access to copy the source code from the same place counts as
      distribution of the source code, even though third parties are not
      compelled to copy the source along with the object code.
       
      4. You may not copy, modify, sublicense, or distribute the Program
      except as expressly provided under this License. Any attempt
      otherwise to copy, modify, sublicense or distribute the Program is
      void, and will automatically terminate your rights under this License.
      However, parties who have received copies, or rights, from you under
      this License will not have their licenses terminated so long as such
      parties remain in full compliance.
       
      5. You are not required to accept this License, since you have not
      signed it. However, nothing else grants you permission to modify or
      distribute the Program or its derivative works. These actions are
      prohibited by law if you do not accept this License. Therefore, by
      modifying or distributing the Program (or any work based on the
      Program), you indicate your acceptance of this License to do so, and
      all its terms and conditions for copying, distributing or modifying
      the Program or works based on it.
       
      6. Each time you redistribute the Program (or any work based on the
      Program), the recipient automatically receives a license from the
      original licensor to copy, distribute or modify the Program subject to
      these terms and conditions. You may not impose any further
      restrictions on the recipients’ exercise of the rights granted herein.
      You are not responsible for enforcing compliance by third parties to
      this License.
       
      7. If, as a consequence of a court judgment or allegation of patent
      infringement or for any other reason (not limited to patent issues),
      conditions are imposed on you (whether by court order, agreement or
      otherwise) that contradict the conditions of this License, they do not
      excuse you from the conditions of this License. If you cannot
      distribute so as to satisfy simultaneously your obligations under this
      License and any other pertinent obligations, then as a consequence you
      may not distribute the Program at all. For example, if a patent
      license would not permit royalty-free redistribution of the Program by
      all those who receive copies directly or indirectly through you, then
      the only way you could satisfy both it and this License would be to
      refrain entirely from distribution of the Program.
       
      If any portion of this section is held invalid or unenforceable under
      any particular circumstance, the balance of the section is intended to
      apply and the section as a whole is intended to apply in other
      circumstances.
       
      It is not the purpose of this section to induce you to infringe any
      patents or other property right claims or to contest validity of any
      such claims; this section has the sole purpose of protecting the
      integrity of the free software distribution system, which is
      implemented by public license practices. Many people have made
      generous contributions to the wide range of software distributed
      through that system in reliance on consistent application of that
      system; it is up to the author/donor to decide if he or she is willing
      to distribute software through any other system and a licensee cannot
      impose that choice.
       
      This section is intended to make thoroughly clear what is believed to
      be a consequence of the rest of this License.
       
      8. If the distribution and/or use of the Program is restricted in
      certain countries either by patents or by copyrighted interfaces, the
      original copyright holder who places the Program under this License
      may add an explicit geographical distribution limitation excluding
      those countries, so that distribution is permitted only in or among
      countries not thus excluded. In such case, this License incorporates
      the limitation as if written in the body of this License.
       
      9. The Free Software Foundation may publish revised and/or new versions
      of the General Public License from time to time. Such new versions will
      be similar in spirit to the present version, but may differ in detail to
      address new problems or concerns.
       
      Each version is given a distinguishing version number. If the Program
      specifies a version number of this License which applies to it and “any
      later version”, you have the option of following the terms and conditions
      either of that version or of any later version published by the Free
      Software Foundation. If the Program does not specify a version number of
      this License, you may choose any version ever published by the Free Software
      Foundation.
       
      10. If you wish to incorporate parts of the Program into other free
      programs whose distribution conditions are different, write to the author
      to ask for permission. For software which is copyrighted by the Free
      Software Foundation, write to the Free Software Foundation; we sometimes
      make exceptions for this. Our decision will be guided by the two goals
      of preserving the free status of all derivatives of our free software and
      of promoting the sharing and reuse of software generally.
       
      NO WARRANTY
       
      11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
      FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
      OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
      PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
      OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
      MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
      TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
      PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
      REPAIR OR CORRECTION.
       
      12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
      WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
      REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
      INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
      OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
      TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
      YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
      PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
      POSSIBILITY OF SUCH DAMAGES.
       
      END OF TERMS AND CONDITIONS
       
      How to Apply These Terms to Your New Programs
       
      If you develop a new program, and you want it to be of the greatest
      possible use to the public, the best way to achieve this is to make it
      free software which everyone can redistribute and change under these terms.
       
      To do so, attach the following notices to the program. It is safest
      to attach them to the start of each source file to most effectively
      convey the exclusion of warranty; and each file should have at least
      the “copyright” line and a pointer to where the full notice is found.
       
      <one line to give the program’s name and a brief idea of what it does.>
      Copyright (C)
       
      This program is free software; you can redistribute it and/or modify
      it under the terms of the GNU General Public License as published by
      the Free Software Foundation; either version 2 of the License, or
      (at your option) any later version.
       
      This program is distributed in the hope that it will be useful,
      but WITHOUT ANY WARRANTY; without even the implied warranty of
      MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
      GNU General Public License for more details.
       
      You should have received a copy of the GNU General Public License
      along with this program; if not, write to the Free Software
      Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
       
       
      Also add information on how to contact you by electronic and paper mail.
       
      If the program is interactive, make it output a short notice like this
      when it starts in an interactive mode:
       
      Gnomovision version 69, Copyright (C) year name of author
      Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w’.
      This is free software, and you are welcome to redistribute it
      under certain conditions; type `show c’ for details.
       
      The hypothetical commands show w' and show c’ should show the appropriate
      parts of the General Public License. Of course, the commands you use may
      be called something other than show w' and show c’; they could even be
      mouse-clicks or menu items–whatever suits your program.
       
      You should also get your employer (if you work as a programmer) or your
      school, if any, to sign a “copyright disclaimer” for the program, if
      necessary. Here is a sample; alter the names:
       
      Yoyodyne, Inc., hereby disclaims all copyright interest in the program
      `Gnomovision’ (which makes passes at compilers) written by James Hacker.
       
      , 1 April 1989
      Ty Coon, President of Vice
       
      This General Public License does not permit incorporating your program into
      proprietary programs. If your program is a subroutine library, you may
      consider it more useful to permit linking proprietary applications with the
      library. If this is what you want to do, use the GNU Library General
      Public License instead of this License.

      1. We don’t promise that this software works. (But if you find any bugs,
      please let us know!)
      2. You can use this software for whatever you want. You don’t have to pay us.
      3. You may not pretend that you wrote this software. If you use it in a
      program, you must acknowledge somewhere in your documentation that
      you’ve used the IJG code.
       
      In legalese:
       
      The authors make NO WARRANTY or representation, either express or implied,
      with respect to this software, its quality, accuracy, merchantability, or
      fitness for a particular purpose. This software is provided “AS IS”, and you,
      its user, assume the entire risk as to its quality and accuracy.

      All Rights Reserved except as specified below.
       
      Permission is hereby granted to use, copy, modify, and distribute this
      software (or portions thereof) for any purpose, without fee, subject to these
      conditions:
      (1) If any part of the source code for this software is distributed, then this
      README file must be included, with this copyright and no-warranty notice
      unaltered; and any additions, deletions, or changes to the original files
      must be clearly indicated in accompanying documentation.
      (2) If only executable code is distributed, then the accompanying
      documentation must state that “this software is based in part on the work of
      the Independent JPEG Group”.
      (3) Permission for use of this software is granted only if the user accepts
      full responsibility for any undesirable consequences; the authors accept
      NO LIABILITY for damages of any kind.
       
      These conditions apply to any software derived from or based on the IJG code,
      not just to the unmodified library. If you use our work, you ought to
      acknowledge us.
       
      Permission is NOT granted for the use of any IJG author’s name or company name
      in advertising or publicity relating to this software or products derived from
      it. This software may be referred to only as “the Independent JPEG Group’s
      software”.

      commercial products, provided that all warranty or liability claims are
      assumed by the product vendor.
       
      libjpeg-turbo Licenses
       
      libjpeg-turbo is covered by two compatible BSD-style open source licenses:
       
      - The IJG (Independent JPEG Group) License, which is listed in
      README.ijg
       
      This license applies to the libjpeg API library and associated programs,
      including any code inherited from libjpeg and any modifications to that
      code. Note that the libjpeg-turbo SIMD source code bears the
      zlib License, but in the context of
      the overall libjpeg API library, the terms of the zlib License are subsumed
      by the terms of the IJG License.
       
      - The Modified (3-clause) BSD License, which is listed below
       
      This license applies to the TurboJPEG API library and associated programs, as
      well as the build system. Note that the TurboJPEG API library wraps the
      libjpeg API library, so in the context of the overall TurboJPEG API library,
      both the terms of the IJG License and the terms of the Modified (3-clause)
      BSD License apply.
       
       
      Complying with the libjpeg-turbo Licenses
       
      This section provides a roll-up of the libjpeg-turbo licensing terms, to the
      best of our understanding. This is not a license in and of itself. It is
      intended solely for clarification.
       
      1. If you are distributing a modified version of the libjpeg-turbo source,
      then:
       
      1. You cannot alter or remove any existing copyright or license notices
      from the source.
       
      Origin
      - Clause 1 of the IJG License
      - Clause 1 of the Modified BSD License
      - Clauses 1 and 3 of the zlib License
       
      2. You must add your own copyright notice to the header of each source
      file you modified, so others can tell that you modified that file. (If
      there is not an existing copyright header in that file, then you can
      simply add a notice stating that you modified the file.)
       
      Origin
      - Clause 1 of the IJG License
      - Clause 2 of the zlib License
       
      3. You must include the IJG README file, and you must not alter any of the
      copyright or license text in that file.
       
      Origin
      - Clause 1 of the IJG License
       
      2. If you are distributing only libjpeg-turbo binaries without the source, or
      if you are distributing an application that statically links with
      libjpeg-turbo, then:
       
      1. Your product documentation must include a message stating:
       
      This software is based in part on the work of the Independent JPEG
      Group.
       
      Origin
      - Clause 2 of the IJG license
       
      2. If your binary distribution includes or uses the TurboJPEG API, then
      your product documentation must include the text of the Modified BSD
      License (see below.)
       
      Origin
      - Clause 2 of the Modified BSD License
       
      3. You cannot use the name of the IJG or The libjpeg-turbo Project or the
      contributors thereof in advertising, publicity, etc.
       
      Origin
      - IJG License
      - Clause 3 of the Modified BSD License
       
      4. The IJG and The libjpeg-turbo Project do not warrant libjpeg-turbo to be
      free of defects, nor do we accept any liability for undesirable
      consequences resulting from your use of the software.
       
      Origin
      - IJG License
      - Modified BSD License
      - zlib License

      Why Two Licenses?
       
      The zlib License could have been used instead of the Modified (3-clause) BSD
      License, and since the IJG License effectively subsumes the distribution
      conditions of the zlib License, this would have effectively placed
      libjpeg-turbo binary distributions under the IJG License. However, the IJG
      License specifically refers to the Independent JPEG Group and does not extend
      attribution and endorsement protections to other entities. Thus, it was
      desirable to choose a license that granted us the same protections for new code
      that were granted to the IJG for code derived from their software.

      ===== xz-5.4.5 =====
       
       
      XZ Utils Licensing
       
      Different licenses apply to different files in this package. Here
      is a rough summary of which licenses apply to which parts of this
      package (but check the individual files to be sure!):
       
      - liblzma is in the public domain.
       
      - xz, xzdec, and lzmadec command line tools are in the public
      domain unless GNU getopt_long had to be compiled and linked
      in from the lib directory. The getopt_long code is under
      GNU LGPLv2.1+.
       
      - The scripts to grep, diff, and view compressed files have been
      adapted from gzip. These scripts and their documentation are
      under GNU GPLv2+.
       
      - All the documentation in the doc directory and most of the
      XZ Utils specific documentation files in other directories
      are in the public domain.
       
      Note: The JavaScript files (under the MIT license) have
      been removed from the Doxygen-generated HTML version of the
      liblzma API documentation. Doxygen itself is under the GNU GPL
      but the remaining files generated by Doxygen are not affected
      by the licenses used in Doxygen because Doxygen licensing has
      the following exception:
       
      “Documents produced by doxygen are derivative works
      derived from the input used in their production;
      they are not affected by this license.”
       
      - Translated messages are in the public domain.
       
      - The build system contains public domain files, and files that
      are under GNU GPLv2+ or GNU GPLv3+. None of these files end up
      in the binaries being built.
       
      - Test files and test code in the tests directory, and debugging
      utilities in the debug directory are in the public domain.
       
      - The extra directory may contain public domain files, and files
      that are under various free software licenses.
       
      You can do whatever you want with the files that have been put into
      the public domain. If you find public domain legally problematic,
      take the previous sentence as a license grant. If you still find
      the lack of copyright legally problematic, you have too many
      lawyers.
       
      As usual, this software is provided “as is”, without any warranty.
       
      If you copy significant amounts of public domain code from XZ Utils
      into your project, acknowledging this somewhere in your software is
      polite (especially if it is proprietary, non-free software), but
      naturally it is not legally required. Here is an example of a good
      notice to put into “about box” or into documentation:
       
      This software includes code from XZ Utils https://tukaani.org/xz/.
       
      The following license texts are included in the following files:
      - COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1
      - COPYING.GPLv2: GNU General Public License version 2
      - COPYING.GPLv3: GNU General Public License version 3
       
      Note that the toolchain (compiler, linker etc.) may add some code
      pieces that are copyrighted. Thus, it is possible that e.g. liblzma
      binary wouldn’t actually be in the public domain in its entirety
      even though it contains no copyrighted code from the XZ Utils source
      package.
       
      If you have questions, don’t hesitate to ask the author(s) for more
      information.

pyinstaller 6.13.0 GNU General Public License v2 (GPLv2) ================================
      The PyInstaller licensing terms
       
       
      Copyright (c) 2010-2023, PyInstaller Development Team
      Copyright (c) 2005-2009, Giovanni Bajo
      Based on previous work under copyright (c) 2002 McMillan Enterprises, Inc.
       
       
      PyInstaller is licensed under the terms of the GNU General Public License
      as published by the Free Software Foundation; either version 2 of the License,
      or (at your option) any later version.
       
       
      Bootloader Exception
       
      In addition to the permissions in the GNU General Public License, the
      authors give you unlimited permission to link or embed compiled bootloader
      and related files into combinations with other programs, and to distribute
      those combinations without any restriction coming from the use of those
      files. (The General Public License restrictions do apply in other respects;
      for example, they cover modification of the files, and distribution when
      not linked into a combined executable.)
       
       
      Bootloader and Related Files
       
      Bootloader and related files are files which are embedded within the
      final executable. This includes files in directories:
       
      ./bootloader/
      ./PyInstaller/loader
       
       
      Run-time Hooks
       
      Run-time Hooks are a different kind of files embedded within the final
      executable. To ease moving them into a separate repository, or into the
      respective project, these files are now licensed under the Apache License,
      Version 2.0.
       
      Run-time Hooks are in the directory
      ./PyInstaller/hooks/rthooks
       
       
      The PyInstaller.isolated submodule
       
      By request, the PyInstaller.isolated submodule and its corresponding tests are
      additionally licensed with the MIT license so that it may be reused outside of
      PyInstaller under GPL 2.0 or MIT terms and conditions – whichever is the most
      suitable to the recipient downstream project. Affected files/directories are:
       
      ./PyInstaller/isolated/
      ./tests/unit/test_isolation.py
       
       
      About the PyInstaller Development Team
       
      The PyInstaller Development Team is the set of contributors
      to the PyInstaller project. A full list with details is kept
      in the documentation directory, in the file
      doc/CREDITS.rst.
       
      The core team that coordinates development on GitHub can be found here:
      https://github.com/pyinstaller/pyinstaller. As of 2021, it consists of:
       
      * Hartmut Goebel
      * Jasper Harrison
      * Bryan Jones
      * Brenainn Woodsend
      * Rok Mandeljc
       
      Our Copyright Policy
       
      PyInstaller uses a shared copyright model. Each contributor maintains copyright
      over their contributions to PyInstaller. But, it is important to note that these
      contributions are typically only changes to the repositories. Thus,
      the PyInstaller source code, in its entirety is not the copyright of any single
      person or institution. Instead, it is the collective copyright of the entire
      PyInstaller Development Team. If individual contributors want to maintain
      a record of what changes/contributions they have specific copyright on, they
      should indicate their copyright in the commit message of the change, when they
      commit the change to the PyInstaller repository.
       
      With this in mind, the following banner should be used in any source code file
      to indicate the copyright and license terms:
       
       
      #—————————————————————————–
      # Copyright (c) 2005-2023, PyInstaller Development Team.
      #
      # Distributed under the terms of the GNU General Public License (version 2
      # or later) with exception for distributing the bootloader.

      # The full license is in the file COPYING.txt, distributed with this software.
      #
      # SPDX-License-Identifier: (GPL-2.0-or-later WITH Bootloader-exception)

      freedom to share and change it. By contrast, the GNU General Public
      License is intended to guarantee your freedom to share and change free
      software–to make sure the software is free for all its users. This
      General Public License applies to most of the Free Software
      Foundation’s software and to any other program whose authors commit to
      using it. (Some other Free Software Foundation software is covered by
      the GNU Library General Public License instead.) You can apply it to
      your programs, too.
       
      When we speak of free software, we are referring to freedom, not
      price. Our General Public Licenses are designed to make sure that you
      have the freedom to distribute copies of free software (and charge for
      this service if you wish), that you receive source code or can get it
      if you want it, that you can change the software or use pieces of it
      in new free programs; and that you know you can do these things.
       
      To protect your rights, we need to make restrictions that forbid
      anyone to deny you these rights or to ask you to surrender the rights.
      These restrictions translate to certain responsibilities for you if you
      distribute copies of the software, or if you modify it.
       
      For example, if you distribute copies of such a program, whether
      gratis or for a fee, you must give the recipients all the rights that
      you have. You must make sure that they, too, receive or can get the
      source code. And you must show them these terms so they know their
      rights.
       
      We protect your rights with two steps: (1) copyright the software, and
      (2) offer you this license which gives you legal permission to copy,
      distribute and/or modify the software.
       
      Also, for each author’s protection and ours, we want to make certain
      that everyone understands that there is no warranty for this free
      software. If the software is modified by someone else and passed on, we
      want its recipients to know that what they have is not the original, so
      that any problems introduced by others will not reflect on the original
      authors’ reputations.
       
      Finally, any free program is threatened constantly by software
      patents. We wish to avoid the danger that redistributors of a free
      program will individually obtain patent licenses, in effect making the
      program proprietary. To prevent this, we have made it clear that any
      patent must be licensed for everyone’s free use or not licensed at all.
       
      The precise terms and conditions for copying, distribution and
      modification follow.
       
      GNU GENERAL PUBLIC LICENSE
      TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
       
      0. This License applies to any program or other work which contains
      a notice placed by the copyright holder saying it may be distributed
      under the terms of this General Public License. The “Program”, below,
      refers to any such program or work, and a “work based on the Program”
      means either the Program or any derivative work under copyright law:
      that is to say, a work containing the Program or a portion of it,
      either verbatim or with modifications and/or translated into another
      language. (Hereinafter, translation is included without limitation in
      the term “modification”.) Each licensee is addressed as “you”.
       
      Activities other than copying, distribution and modification are not
      covered by this License; they are outside its scope. The act of
      running the Program is not restricted, and the output from the Program
      is covered only if its contents constitute a work based on the
      Program (independent of having been made by running the Program).
      Whether that is true depends on what the Program does.
       
      1. You may copy and distribute verbatim copies of the Program’s
      source code as you receive it, in any medium, provided that you
      conspicuously and appropriately publish on each copy an appropriate
      copyright notice and disclaimer of warranty; keep intact all the
      notices that refer to this License and to the absence of any warranty;
      and give any other recipients of the Program a copy of this License
      along with the Program.
       
      You may charge a fee for the physical act of transferring a copy, and
      you may at your option offer warranty protection in exchange for a fee.
       
      2. You may modify your copy or copies of the Program or any portion
      of it, thus forming a work based on the Program, and copy and
      distribute such modifications or work under the terms of Section 1
      above, provided that you also meet all of these conditions:
       
      a) You must cause the modified files to carry prominent notices
      stating that you changed the files and the date of any change.
       
      b) You must cause any work that you distribute or publish, that in
      whole or in part contains or is derived from the Program or any
      part thereof, to be licensed as a whole at no charge to all third
      parties under the terms of this License.
       
      c) If the modified program normally reads commands interactively
      when run, you must cause it, when started running for such
      interactive use in the most ordinary way, to print or display an
      announcement including an appropriate copyright notice and a
      notice that there is no warranty (or else, saying that you provide
      a warranty) and that users may redistribute the program under
      these conditions, and telling the user how to view a copy of this
      License. (Exception: if the Program itself is interactive but
      does not normally print such an announcement, your work based on
      the Program is not required to print an announcement.)
       
      These requirements apply to the modified work as a whole. If
      identifiable sections of that work are not derived from the Program,
      and can be reasonably considered independent and separate works in
      themselves, then this License, and its terms, do not apply to those
      sections when you distribute them as separate works. But when you
      distribute the same sections as part of a whole which is a work based
      on the Program, the distribution of the whole must be on the terms of
      this License, whose permissions for other licensees extend to the
      entire whole, and thus to each and every part regardless of who wrote it.
       
      Thus, it is not the intent of this section to claim rights or contest
      your rights to work written entirely by you; rather, the intent is to
      exercise the right to control the distribution of derivative or
      collective works based on the Program.
       
      In addition, mere aggregation of another work not based on the Program
      with the Program (or with a work based on the Program) on a volume of
      a storage or distribution medium does not bring the other work under
      the scope of this License.
       
      3. You may copy and distribute the Program (or a work based on it,
      under Section 2) in object code or executable form under the terms of
      Sections 1 and 2 above provided that you also do one of the following:
       
      a) Accompany it with the complete corresponding machine-readable
      source code, which must be distributed under the terms of Sections
      1 and 2 above on a medium customarily used for software interchange; or,
       
      b) Accompany it with a written offer, valid for at least three
      years, to give any third party, for a charge no more than your
      cost of physically performing source distribution, a complete
      machine-readable copy of the corresponding source code, to be
      distributed under the terms of Sections 1 and 2 above on a medium
      customarily used for software interchange; or,
       
      c) Accompany it with the information you received as to the offer
      to distribute corresponding source code. (This alternative is
      allowed only for noncommercial distribution and only if you
      received the program in object code or executable form with such
      an offer, in accord with Subsection b above.)
       
      The source code for a work means the preferred form of the work for
      making modifications to it. For an executable work, complete source
      code means all the source code for all modules it contains, plus any
      associated interface definition files, plus the scripts used to
      control compilation and installation of the executable. However, as a
      special exception, the source code distributed need not include
      anything that is normally distributed (in either source or binary
      form) with the major components (compiler, kernel, and so on) of the
      operating system on which the executable runs, unless that component
      itself accompanies the executable.
       
      If distribution of executable or object code is made by offering
      access to copy from a designated place, then offering equivalent
      access to copy the source code from the same place counts as
      distribution of the source code, even though third parties are not
      compelled to copy the source along with the object code.
       
      4. You may not copy, modify, sublicense, or distribute the Program
      except as expressly provided under this License. Any attempt
      otherwise to copy, modify, sublicense or distribute the Program is
      void, and will automatically terminate your rights under this License.
      However, parties who have received copies, or rights, from you under
      this License will not have their licenses terminated so long as such
      parties remain in full compliance.
       
      5. You are not required to accept this License, since you have not
      signed it. However, nothing else grants you permission to modify or
      distribute the Program or its derivative works. These actions are
      prohibited by law if you do not accept this License. Therefore, by
      modifying or distributing the Program (or any work based on the
      Program), you indicate your acceptance of this License to do so, and
      all its terms and conditions for copying, distributing or modifying
      the Program or works based on it.
       
      6. Each time you redistribute the Program (or any work based on the
      Program), the recipient automatically receives a license from the
      original licensor to copy, distribute or modify the Program subject to
      these terms and conditions. You may not impose any further
      restrictions on the recipients’ exercise of the rights granted herein.
      You are not responsible for enforcing compliance by third parties to
      this License.
       
      7. If, as a consequence of a court judgment or allegation of patent
      infringement or for any other reason (not limited to patent issues),
      conditions are imposed on you (whether by court order, agreement or
      otherwise) that contradict the conditions of this License, they do not
      excuse you from the conditions of this License. If you cannot
      distribute so as to satisfy simultaneously your obligations under this
      License and any other pertinent obligations, then as a consequence you
      may not distribute the Program at all. For example, if a patent
      license would not permit royalty-free redistribution of the Program by
      all those who receive copies directly or indirectly through you, then
      the only way you could satisfy both it and this License would be to
      refrain entirely from distribution of the Program.
       
      If any portion of this section is held invalid or unenforceable under
      any particular circumstance, the balance of the section is intended to
      apply and the section as a whole is intended to apply in other
      circumstances.
       
      It is not the purpose of this section to induce you to infringe any
      patents or other property right claims or to contest validity of any
      such claims; this section has the sole purpose of protecting the
      integrity of the free software distribution system, which is
      implemented by public license practices. Many people have made
      generous contributions to the wide range of software distributed
      through that system in reliance on consistent application of that
      system; it is up to the author/donor to decide if he or she is willing
      to distribute software through any other system and a licensee cannot
      impose that choice.
       
      This section is intended to make thoroughly clear what is believed to
      be a consequence of the rest of this License.
       
      8. If the distribution and/or use of the Program is restricted in
      certain countries either by patents or by copyrighted interfaces, the
      original copyright holder who places the Program under this License
      may add an explicit geographical distribution limitation excluding
      those countries, so that distribution is permitted only in or among
      countries not thus excluded. In such case, this License incorporates
      the limitation as if written in the body of this License.
       
      9. The Free Software Foundation may publish revised and/or new versions
      of the General Public License from time to time. Such new versions will
      be similar in spirit to the present version, but may differ in detail to
      address new problems or concerns.
       
      Each version is given a distinguishing version number. If the Program
      specifies a version number of this License which applies to it and “any
      later version”, you have the option of following the terms and conditions
      either of that version or of any later version published by the Free
      Software Foundation. If the Program does not specify a version number of
      this License, you may choose any version ever published by the Free Software
      Foundation.
       
      10. If you wish to incorporate parts of the Program into other free
      programs whose distribution conditions are different, write to the author
      to ask for permission. For software which is copyrighted by the Free
      Software Foundation, write to the Free Software Foundation; we sometimes
      make exceptions for this. Our decision will be guided by the two goals
      of preserving the free status of all derivatives of our free software and
      of promoting the sharing and reuse of software generally.
       
      NO WARRANTY
       
      11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
      FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
      OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
      PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
      OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
      MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
      TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
      PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
      REPAIR OR CORRECTION.
       
      12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
      WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
      REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
      INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
      OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
      TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
      YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
      PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
      POSSIBILITY OF SUCH DAMAGES.

      and conversions to other media types.
       
      “Work” shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).
       
      “Derivative Works” shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.
       
      “Contribution” shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, “submitted”
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as “Not a Contribution.”
       
      “Contributor” shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.
       
      2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.
       
      3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.
       
      4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:
       
      (a) You must give any other recipients of the Work or
      Derivative Works a copy of this License; and
       
      (b) You must cause any modified files to carry prominent notices
      stating that You changed the files; and
       
      (c) You must retain, in the Source form of any Derivative Works
      that You distribute, all copyright, patent, trademark, and
      attribution notices from the Source form of the Work,
      excluding those notices that do not pertain to any part of
      the Derivative Works; and
       
      (d) If the Work includes a “NOTICE” text file as part of its
      distribution, then any Derivative Works that You distribute must
      include a readable copy of the attribution notices contained
      within such NOTICE file, excluding those notices that do not
      pertain to any part of the Derivative Works, in at least one
      of the following places: within a NOTICE text file distributed
      as part of the Derivative Works; within the Source form or
      documentation, if provided along with the Derivative Works; or,
      within a display generated by the Derivative Works, if and
      wherever such third-party notices normally appear. The contents
      of the NOTICE file are for informational purposes only and
      do not modify the License. You may add Your own attribution
      notices within Derivative Works that You distribute, alongside
      or as an addendum to the NOTICE text from the Work, provided
      that such additional attribution notices cannot be construed
      as modifying the License.
       
      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.
       
      5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.
       
      6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.
       
      7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an “AS IS” BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.
       
      8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.
       
      9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
       
      END OF TERMS AND CONDITIONS

      Copyright (C) 1989, 1991 Free Software Foundation, Inc.
      51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
      Everyone is permitted to copy and distribute verbatim copies
      of this license document, but changing it is not allowed.
       
      Preamble
       
      The licenses for most software are designed to take away your
      freedom to share and change it. By contrast, the GNU General Public
      License is intended to guarantee your freedom to share and change free
      software–to make sure the software is free for all its users. This
      General Public License applies to most of the Free Software
      Foundation’s software and to any other program whose authors commit to
      using it. (Some other Free Software Foundation software is covered by
      the GNU Library General Public License instead.) You can apply it to
      your programs, too.
       
      When we speak of free software, we are referring to freedom, not
      price. Our General Public Licenses are designed to make sure that you
      have the freedom to distribute copies of free software (and charge for
      this service if you wish), that you receive source code or can get it
      if you want it, that you can change the software or use pieces of it
      in new free programs; and that you know you can do these things.
       
      To protect your rights, we need to make restrictions that forbid
      anyone to deny you these rights or to ask you to surrender the rights.
      These restrictions translate to certain responsibilities for you if you
      distribute copies of the software, or if you modify it.
       
      For example, if you distribute copies of such a program, whether
      gratis or for a fee, you must give the recipients all the rights that
      you have. You must make sure that they, too, receive or can get the
      source code. And you must show them these terms so they know their
      rights.
       
      We protect your rights with two steps: (1) copyright the software, and
      (2) offer you this license which gives you legal permission to copy,
      distribute and/or modify the software.
       
      Also, for each author’s protection and ours, we want to make certain
      that everyone understands that there is no warranty for this free
      software. If the software is modified by someone else and passed on, we
      want its recipients to know that what they have is not the original, so
      that any problems introduced by others will not reflect on the original
      authors’ reputations.
       
      Finally, any free program is threatened constantly by software
      patents. We wish to avoid the danger that redistributors of a free
      program will individually obtain patent licenses, in effect making the
      program proprietary. To prevent this, we have made it clear that any
      patent must be licensed for everyone’s free use or not licensed at all.
       
      The precise terms and conditions for copying, distribution and
      modification follow.
       
      GNU GENERAL PUBLIC LICENSE
      TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
       
      0. This License applies to any program or other work which contains
      a notice placed by the copyright holder saying it may be distributed
      under the terms of this General Public License. The “Program”, below,
      refers to any such program or work, and a “work based on the Program”
      means either the Program or any derivative work under copyright law:
      that is to say, a work containing the Program or a portion of it,
      either verbatim or with modifications and/or translated into another
      language. (Hereinafter, translation is included without limitation in
      the term “modification”.) Each licensee is addressed as “you”.
       
      Activities other than copying, distribution and modification are not
      covered by this License; they are outside its scope. The act of
      running the Program is not restricted, and the output from the Program
      is covered only if its contents constitute a work based on the
      Program (independent of having been made by running the Program).
      Whether that is true depends on what the Program does.
       
      1. You may copy and distribute verbatim copies of the Program’s
      source code as you receive it, in any medium, provided that you
      conspicuously and appropriately publish on each copy an appropriate
      copyright notice and disclaimer of warranty; keep intact all the
      notices that refer to this License and to the absence of any warranty;
      and give any other recipients of the Program a copy of this License
      along with the Program.
       
      You may charge a fee for the physical act of transferring a copy, and
      you may at your option offer warranty protection in exchange for a fee.
       
      2. You may modify your copy or copies of the Program or any portion
      of it, thus forming a work based on the Program, and copy and
      distribute such modifications or work under the terms of Section 1
      above, provided that you also meet all of these conditions:
       
      a) You must cause the modified files to carry prominent notices
      stating that you changed the files and the date of any change.
       
      b) You must cause any work that you distribute or publish, that in
      whole or in part contains or is derived from the Program or any
      part thereof, to be licensed as a whole at no charge to all third
      parties under the terms of this License.
       
      c) If the modified program normally reads commands interactively
      when run, you must cause it, when started running for such
      interactive use in the most ordinary way, to print or display an
      announcement including an appropriate copyright notice and a
      notice that there is no warranty (or else, saying that you provide
      a warranty) and that users may redistribute the program under
      these conditions, and telling the user how to view a copy of this
      License. (Exception: if the Program itself is interactive but
      does not normally print such an announcement, your work based on
      the Program is not required to print an announcement.)
       
      These requirements apply to the modified work as a whole. If
      identifiable sections of that work are not derived from the Program,
      and can be reasonably considered independent and separate works in
      themselves, then this License, and its terms, do not apply to those
      sections when you distribute them as separate works. But when you
      distribute the same sections as part of a whole which is a work based
      on the Program, the distribution of the whole must be on the terms of
      this License, whose permissions for other licensees extend to the
      entire whole, and thus to each and every part regardless of who wrote it.
       
      Thus, it is not the intent of this section to claim rights or contest
      your rights to work written entirely by you; rather, the intent is to
      exercise the right to control the distribution of derivative or
      collective works based on the Program.
       
      In addition, mere aggregation of another work not based on the Program
      with the Program (or with a work based on the Program) on a volume of
      a storage or distribution medium does not bring the other work under
      the scope of this License.
       
      3. You may copy and distribute the Program (or a work based on it,
      under Section 2) in object code or executable form under the terms of
      Sections 1 and 2 above provided that you also do one of the following:
       
      a) Accompany it with the complete corresponding machine-readable
      source code, which must be distributed under the terms of Sections
      1 and 2 above on a medium customarily used for software interchange; or,
       
      b) Accompany it with a written offer, valid for at least three
      years, to give any third party, for a charge no more than your
      cost of physically performing source distribution, a complete
      machine-readable copy of the corresponding source code, to be
      distributed under the terms of Sections 1 and 2 above on a medium
      customarily used for software interchange; or,
       
      c) Accompany it with the information you received as to the offer
      to distribute corresponding source code. (This alternative is
      allowed only for noncommercial distribution and only if you
      received the program in object code or executable form with such
      an offer, in accord with Subsection b above.)
       
      The source code for a work means the preferred form of the work for
      making modifications to it. For an executable work, complete source
      code means all the source code for all modules it contains, plus any
      associated interface definition files, plus the scripts used to
      control compilation and installation of the executable. However, as a
      special exception, the source code distributed need not include
      anything that is normally distributed (in either source or binary
      form) with the major components (compiler, kernel, and so on) of the
      operating system on which the executable runs, unless that component
      itself accompanies the executable.
       
      If distribution of executable or object code is made by offering
      access to copy from a designated place, then offering equivalent
      access to copy the source code from the same place counts as
      distribution of the source code, even though third parties are not
      compelled to copy the source along with the object code.
       
      4. You may not copy, modify, sublicense, or distribute the Program
      except as expressly provided under this License. Any attempt
      otherwise to copy, modify, sublicense or distribute the Program is
      void, and will automatically terminate your rights under this License.
      However, parties who have received copies, or rights, from you under
      this License will not have their licenses terminated so long as such
      parties remain in full compliance.
       
      5. You are not required to accept this License, since you have not
      signed it. However, nothing else grants you permission to modify or
      distribute the Program or its derivative works. These actions are
      prohibited by law if you do not accept this License. Therefore, by
      modifying or distributing the Program (or any work based on the
      Program), you indicate your acceptance of this License to do so, and
      all its terms and conditions for copying, distributing or modifying
      the Program or works based on it.
       
      6. Each time you redistribute the Program (or any work based on the
      Program), the recipient automatically receives a license from the
      original licensor to copy, distribute or modify the Program subject to
      these terms and conditions. You may not impose any further
      restrictions on the recipients’ exercise of the rights granted herein.
      You are not responsible for enforcing compliance by third parties to
      this License.
       
      7. If, as a consequence of a court judgment or allegation of patent
      infringement or for any other reason (not limited to patent issues),
      conditions are imposed on you (whether by court order, agreement or
      otherwise) that contradict the conditions of this License, they do not
      excuse you from the conditions of this License. If you cannot
      distribute so as to satisfy simultaneously your obligations under this
      License and any other pertinent obligations, then as a consequence you
      may not distribute the Program at all. For example, if a patent
      license would not permit royalty-free redistribution of the Program by
      all those who receive copies directly or indirectly through you, then
      the only way you could satisfy both it and this License would be to
      refrain entirely from distribution of the Program.
       
      If any portion of this section is held invalid or unenforceable under
      any particular circumstance, the balance of the section is intended to
      apply and the section as a whole is intended to apply in other
      circumstances.
       
      It is not the purpose of this section to induce you to infringe any
      patents or other property right claims or to contest validity of any
      such claims; this section has the sole purpose of protecting the
      integrity of the free software distribution system, which is
      implemented by public license practices. Many people have made
      generous contributions to the wide range of software distributed
      through that system in reliance on consistent application of that
      system; it is up to the author/donor to decide if he or she is willing
      to distribute software through any other system and a licensee cannot
      impose that choice.
       
      This section is intended to make thoroughly clear what is believed to
      be a consequence of the rest of this License.
       
      8. If the distribution and/or use of the Program is restricted in
      certain countries either by patents or by copyrighted interfaces, the
      original copyright holder who places the Program under this License
      may add an explicit geographical distribution limitation excluding
      those countries, so that distribution is permitted only in or among
      countries not thus excluded. In such case, this License incorporates
      the limitation as if written in the body of this License.
       
      9. The Free Software Foundation may publish revised and/or new versions
      of the General Public License from time to time. Such new versions will
      be similar in spirit to the present version, but may differ in detail to
      address new problems or concerns.
       
      Each version is given a distinguishing version number. If the Program
      specifies a version number of this License which applies to it and “any
      later version”, you have the option of following the terms and conditions
      either of that version or of any later version published by the Free
      Software Foundation. If the Program does not specify a version number of
      this License, you may choose any version ever published by the Free Software
      Foundation.
       
      10. If you wish to incorporate parts of the Program into other free
      programs whose distribution conditions are different, write to the author
      to ask for permission. For software which is copyrighted by the Free
      Software Foundation, write to the Free Software Foundation; we sometimes
      make exceptions for this. Our decision will be guided by the two goals
      of preserving the free status of all derivatives of our free software and
      of promoting the sharing and reuse of software generally.
       
      NO WARRANTY
       
      11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
      FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
      OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
      PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
      OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
      MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
      TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
      PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
      REPAIR OR CORRECTION.
       
      12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
      WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
      REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
      INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
      OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
      TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
      YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
      PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
      POSSIBILITY OF SUCH DAMAGES.

      source, and configuration files.
       
      “Object” form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.
       
      “Work” shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).
       
      “Derivative Works” shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.
       
      “Contribution” shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, “submitted”
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as “Not a Contribution.”
       
      “Contributor” shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.
       
      2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.
       
      3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.
       
      4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:
       
      (a) You must give any other recipients of the Work or
      Derivative Works a copy of this License; and
       
      (b) You must cause any modified files to carry prominent notices
      stating that You changed the files; and
       
      (c) You must retain, in the Source form of any Derivative Works
      that You distribute, all copyright, patent, trademark, and
      attribution notices from the Source form of the Work,
      excluding those notices that do not pertain to any part of
      the Derivative Works; and
       
      (d) If the Work includes a “NOTICE” text file as part of its
      distribution, then any Derivative Works that You distribute must
      include a readable copy of the attribution notices contained
      within such NOTICE file, excluding those notices that do not
      pertain to any part of the Derivative Works, in at least one
      of the following places: within a NOTICE text file distributed
      as part of the Derivative Works; within the Source form or
      documentation, if provided along with the Derivative Works; or,
      within a display generated by the Derivative Works, if and
      wherever such third-party notices normally appear. The contents
      of the NOTICE file are for informational purposes only and
      do not modify the License. You may add Your own attribution
      notices within Derivative Works that You distribute, alongside
      or as an addendum to the NOTICE text from the Work, provided
      that such additional attribution notices cannot be construed
      as modifying the License.
       
      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.
       
      5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.
       
      6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.
       
      7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an “AS IS” BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.
       
      8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.
       
      9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
       
      END OF TERMS AND CONDITIONS
