    direction or management of such entity, whether by contract or
    otherwise, or (ii) ownership of fifty percent (50%) or more of the

    "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

    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.

    This file is part of the Independent JPEG Group's software.
    For conditions of distribution and use, see the accompanying README file.

    [relevant README excerpt]

    In plain English:

    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.

    This software is copyright (C) 1991-2016, Thomas G. Lane, Guido Vollbeding.
    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".

    We specifically permit and encourage the use of this software as the basis of
    commercial products, provided that all warranty or liability claims are
    assumed by the product vendor.


    The Unix configuration script "configure" was produced with GNU Autoconf.
    It is copyright by the Free Software Foundation but is freely distributable.
    The same holds for its supporting scripts (config.guess, config.sub,
    ltmain.sh).  Another support script, install-sh, is copyright by X Consortium
    but is also freely distributable.

    The IJG distribution formerly included code to read and write GIF files.
    To avoid entanglement with the Unisys LZW patent (now expired), GIF reading
    support has been removed altogether, and the GIF writer has been simplified
    to produce "uncompressed GIFs".  This technique does not use the LZW
    algorithm; the resulting GIF files are larger than usual, but are readable
    by all standard GIF decoders.

          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
          and its affiliates, except as required to comply with Section 4(c) of
          the License and to reproduce 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.
