 Contributing to libjpeg-turbo
 =============================
 libjpeg-turbo is a stable and mature product with a worldwide reach, it is an
 ISO/ITU-T reference implementation of the JPEG standard, and its maintainer
 does not earn a salary for maintaining it.  Thus, not every code contribution
 can or will be accepted into the libjpeg-turbo code base.  In order to maximize
 the chances that a code contribution is acceptable, please adhere to the
 following guidelines:
 1. If the code contribution is a bug fix, then please ensure that enough
 information is provided so that the maintainer can readily reproduce and
 document the bug.  That information should include:
    - A clear and concise description of the bug
    - The steps and (if applicable) images necessary to reproduce the bug
    - The compilers, operating systems, and CPUs with which the bug was
      observed
    - The versions of libjpeg-turbo with which the bug was observed
    - If the bug is a regression, the specific commit that introduced the bug
      (use `git bisect` to determine this)
 2. If the code contribution will implement a major new feature, then please
 contact the project maintainer (through a
 [GitHub issue](https://github.com/libjpeg-turbo/libjpeg-turbo/issues/new),
 [direct e-mail](https://libjpeg-turbo.org/About/Contact), or the
 [libjpeg-turbo-devel mailing list](https://libjpeg-turbo.org/About/MailingLists))
 prior to implementing the feature.  In general, major new features that are
 potentially disruptive to the quality of libjpeg-turbo are unlikely to be
 accepted unless:
    - The new feature is within the existing scope of libjpeg-turbo.
    - The new feature has been thoroughly regression tested and benchmarked on
      all of the supported platforms that are potentially affected by it.
    - The new feature has been documented clearly and concisely in the change
      log and (if applicable) the libjpeg and TurboJPEG API documentation and
      man pages.
    - The code implementing the new feature is formatted consistently with the
      rest of the libjpeg-turbo code base (use
      [checkstyle](https://github.com/libjpeg-turbo/checkstyle) to validate
      this.)
    - The new feature does not introduce new members into the exposed libjpeg
      API structures (doing so would break backward ABI compatibility.)
    - The new feature does not alter existing libjpeg-turbo usage or
      development workflows.
    - The code implementing the new feature is elegant, easily maintainable,
      and causes the least possible amount of disruption to the libjpeg-turbo
      code base.
    - The new feature is based on the dev branch of the libjpeg-turbo
      repository.
    ... OR ...
    - Your organization is prepared to pay for the labor necessary to ensure
      all of the above.  Even the most well-written patches can still require
      a significant amount of labor to clean up, test, and integrate.  (See
      above RE: the maintainer not earning a salary.)
    Specific types of features that *will not* be accepted:
    - Features that extend the scope of libjpeg-turbo to support image formats
      other than DCT-based JPEG and JFIF
    - Features that extend the scope of libjpeg-turbo to support image
      processing algorithms that are not necessary for JPEG compression or
      decompression
    - Extensions to the JPEG format that have not been approved by the
      appropriate standards bodies
    - Non-trivial performance enhancements that have less than a 5% overall
      impact on performance
 3. If the code contribution is a build system enhancement, then please be
 prepared to justify the enhancement.  In general, build system enhancements
 are unlikely to be accepted unless:
    - The enhancement is potentially beneficial to a significant number of
      upstream libjpeg-turbo users/developers.  (If the enhancement is only
      beneficial to a downstream project, then it does not belong here.)
    - The enhancement has been tested with the following CMake versions:
        - The earliest version of CMake that libjpeg-turbo currently supports
          (refer to CMakeLists.txt)
        - The most recent major version of CMake
        - (if applicable) The earliest version of CMake with which the
          enhancement can be used
    - The enhancement has been tested on all of the major platforms (Mac,
      Linux, Windows/Visual C++, Windows/MinGW) that are potentially affected
      by it.
    - The enhancement does not introduce new build system requirements or CMake
      variables unless absolutely necessary.
    - The enhancement does not alter existing libjpeg-turbo development
      workflows.
    Specific types of build system enhancements that *will not* be accepted:
    - Enhancements that allow libjpeg-turbo to be built from a subdirectory
      of a downstream repository.  These enhancements are not maintainable in
      the upstream libjpeg-turbo build system.  Use the CMake
      `ExternalProject_Add()` function instead.
    - Enhancements that introduce new (non-CMake-based) build systems

 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.

 #.rst:
 # GNUInstallDirs
 # --------------
 #
 # Define GNU standard installation directories
 #
 # Provides install directory variables as defined by the
 # `GNU Coding Standards`_.
 #
 # .. _`GNU Coding Standards`: https://www.gnu.org/prep/standards/html_node/Directory-Variables.html
 #
 # Result Variables
 # ^^^^^^^^^^^^^^^^
 #
 # Inclusion of this module defines the following variables:
 #
 # ``CMAKE_INSTALL_<dir>``
 #
 #   Destination for files of a given type.  This value may be passed to
 #   the ``DESTINATION`` options of :command:`install` commands for the
 #   corresponding file type.
 #
 # ``CMAKE_INSTALL_FULL_<dir>``
 #
 #   The absolute path generated from the corresponding ``CMAKE_INSTALL_<dir>``
 #   value.  If the value is not already an absolute path, an absolute path
 #   is constructed typically by prepending the value of the
 #   :variable:`CMAKE_INSTALL_PREFIX` variable.  However, there are some
 #   `special cases`_ as documented below.
 #
 # where ``<dir>`` is one of:
 #
 # ``BINDIR``
 #   user executables (``bin``)
 # ``SBINDIR``
 #   system admin executables (``sbin``)
 # ``LIBEXECDIR``
 #   program executables (``libexec``)
 # ``SYSCONFDIR``
 #   read-only single-machine data (``etc``)
 # ``SHAREDSTATEDIR``
 #   modifiable architecture-independent data (``com``)
 # ``LOCALSTATEDIR``
 #   modifiable single-machine data (``var``)
 # ``LIBDIR``
 #   object code libraries (``lib`` or ``lib64``
 #   or ``lib/<multiarch-tuple>`` on Debian)
 # ``INCLUDEDIR``
 #   C header files (``include``)
 # ``OLDINCLUDEDIR``
 #   C header files for non-gcc (``/usr/include``)
 # ``DATAROOTDIR``
 #   read-only architecture-independent data root (``share``)
 # ``DATADIR``
 #   read-only architecture-independent data (``DATAROOTDIR``)
 # ``INFODIR``
 #   info documentation (``DATAROOTDIR/info``)
 # ``LOCALEDIR``
 #   locale-dependent data (``DATAROOTDIR/locale``)
 # ``MANDIR``
 #   man documentation (``DATAROOTDIR/man``)
 # ``DOCDIR``
 #   documentation root (``DATAROOTDIR/doc/PROJECT_NAME``)
 #
 # If the includer does not define a value the above-shown default will be
 # used and the value will appear in the cache for editing by the user.
 #
 # Special Cases
 # ^^^^^^^^^^^^^
 #
 # The following values of :variable:`CMAKE_INSTALL_PREFIX` are special:
 #
 # ``/``
 #
 #   For ``<dir>`` other than the ``SYSCONFDIR`` and ``LOCALSTATEDIR``,
 #   the value of ``CMAKE_INSTALL_<dir>`` is prefixed with ``usr/`` if
 #   it is not user-specified as an absolute path.  For example, the
 #   ``INCLUDEDIR`` value ``include`` becomes ``usr/include``.
 #   This is required by the `GNU Coding Standards`_, which state:
 #
 #     When building the complete GNU system, the prefix will be empty
 #     and ``/usr`` will be a symbolic link to ``/``.
 #
 # ``/usr``
 #
 #   For ``<dir>`` equal to ``SYSCONFDIR`` or ``LOCALSTATEDIR``, the
 #   ``CMAKE_INSTALL_FULL_<dir>`` is computed by prepending just ``/``
 #   to the value of ``CMAKE_INSTALL_<dir>`` if it is not user-specified
 #   as an absolute path.  For example, the ``SYSCONFDIR`` value ``etc``
 #   becomes ``/etc``.  This is required by the `GNU Coding Standards`_.
 #
 # ``/opt/...``
 #
 #   For ``<dir>`` equal to ``SYSCONFDIR`` or ``LOCALSTATEDIR``, the
 #   ``CMAKE_INSTALL_FULL_<dir>`` is computed by *appending* the prefix
 #   to the value of ``CMAKE_INSTALL_<dir>`` if it is not user-specified
 #   as an absolute path.  For example, the ``SYSCONFDIR`` value ``etc``
 #   becomes ``/etc/opt/...``.  This is defined by the
 #   `Filesystem Hierarchy Standard`_.
 #
 # .. _`Filesystem Hierarchy Standard`: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html
 #
 # Macros
 # ^^^^^^
 #
 # .. command:: GNUInstallDirs_get_absolute_install_dir
 #
 #   ::
 #
 #     GNUInstallDirs_get_absolute_install_dir(absvar var)
 #
 #   Set the given variable ``absvar`` to the absolute path contained
 #   within the variable ``var``.  This is to allow the computation of an
 #   absolute path, accounting for all the special cases documented
 #   above.  While this macro is used to compute the various
 #   ``CMAKE_INSTALL_FULL_<dir>`` variables, it is exposed publicly to
 #   allow users who create additional path variables to also compute
 #   absolute paths where necessary, using the same logic.

 .SH ISSUES
 Support for compressed GIF output files was removed in djpeg v6b due to
 concerns over the Unisys LZW patent.  Although this patent expired in 2006,
 djpeg still lacks compressed GIF support, for these historical reasons.
 (Conversion of JPEG files to GIF is usually a bad idea anyway, since GIF is a
 256-color format.)  The uncompressed GIF files that djpeg generates are larger
 than they should be, but they are readable by standard GIF decoders.
