 Here, glslang proper means core GLSL parsing, HLSL parsing, and SPIR-V code
 generation. Glslang proper requires use of a number of licenses, one that covers
 preprocessing and others that covers non-preprocessing.

 Bison was removed long ago. You can build glslang from the source grammar,
 using tools of your choice, without using bison or any bison files.

 Other parts, outside of glslang proper, include:

 - gl_types.h, only needed for OpenGL-like reflection, and can be left out of
   a parse and codegen project.  See it for its license.

 - update_glslang_sources.py, which is not part of the project proper and does
   not need to be used.

 - the SPIR-V "remapper", which is optional, but has the same license as
   glslang proper

 - Google tests and SPIR-V tools, and anything in the external subdirectory
   are external and optional; see them for their respective licenses.

 The core of glslang-proper, minus the preprocessor is licenced as follows:

       "You" (or "Your") shall mean an individual or Legal Entity
       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

    APPENDIX: How to apply the Apache License to your work.

       To apply the Apache License to your work, attach the following
       boilerplate notice, with the fields enclosed by brackets "[]"
       replaced with your own identifying information. (Don't include
       the brackets!)  The text should be enclosed in the appropriate
       comment syntax for the file format. We also recommend that a
       file or class name and description of purpose be included on the
       same "printed page" as the copyright notice for easier
       identification within third-party archives.

    As a special exception, you may create a larger work that contains
    part or all of the Bison parser skeleton and distribute that work
    under terms of your choice, so long as that work isn't itself a
    parser generator using the skeleton or a modified version thereof
    as a parser skeleton.  Alternatively, if you modify or redistribute
    the parser skeleton itself, you may (at your option) remove this
    special exception, which will cause the skeleton and the resulting
    Bison output files to be licensed under the GNU General Public
    License without this special exception.

    This special exception was added by the Free Software Foundation in
    version 2.2 of Bison.
