+Catch
+-----
+
+This module defines a function to help use the Catch test framework.
+
+The :command:`catch_discover_tests` discovers tests by asking the compiled test
+executable to enumerate its tests.  This does not require CMake to be re-run
+when tests change.  However, it may not work in a cross-compiling environment,
+and setting test properties is less convenient.
+
+This command is intended to replace use of :command:`add_test` to register
+tests, and will create a separate CTest test for each Catch test case.  Note
+that this is in some cases less efficient, as common set-up and tear-down logic
+cannot be shared by multiple test cases executing in the same instance.
+However, it provides more fine-grained pass/fail information to CTest, which is
+usually considered as more beneficial.  By default, the CTest test name is the
+same as the Catch name; see also ``TEST_PREFIX`` and ``TEST_SUFFIX``.
+
+.. command:: catch_discover_tests
+
+  Automatically add tests with CTest by querying the compiled test executable
+  for available tests::
+
+    catch_discover_tests(target
+                         [TEST_SPEC arg1...]
+                         [EXTRA_ARGS arg1...]
+                         [WORKING_DIRECTORY dir]
+                         [TEST_PREFIX prefix]
+                         [TEST_SUFFIX suffix]
+                         [PROPERTIES name1 value1...]
+                         [TEST_LIST var]
+    )
+
+  ``catch_discover_tests`` sets up a post-build command on the test executable
+  that generates the list of tests by parsing the output from running the test
+  with the ``--list-test-names-only`` argument.  This ensures that the full
+  list of tests is obtained.  Since test discovery occurs at build time, it is
+  not necessary to re-run CMake when the list of tests changes.
+  However, it requires that :prop_tgt:`CROSSCOMPILING_EMULATOR` is properly set
+  in order to function in a cross-compiling environment.
+
+  Additionally, setting properties on tests is somewhat less convenient, since
+  the tests are not available at CMake time.  Additional test properties may be
+  assigned to the set of tests as a whole using the ``PROPERTIES`` option.  If
+  more fine-grained test control is needed, custom content may be provided
+  through an external CTest script using the :prop_dir:`TEST_INCLUDE_FILES`
+  directory property.  The set of discovered tests is made accessible to such a
+  script via the ``<target>_TESTS`` variable.
+
+  The options are:
+
+  ``target``
+    Specifies the Catch executable, which must be a known CMake executable
+    target.  CMake will substitute the location of the built executable when
+    running the test.
+
+  ``TEST_SPEC arg1...``
+    Specifies test cases, wildcarded test cases, tags and tag expressions to
+    pass to the Catch executable with the ``--list-test-names-only`` argument.
+
+  ``EXTRA_ARGS arg1...``
+    Any extra arguments to pass on the command line to each test case.
+
+  ``WORKING_DIRECTORY dir``
+    Specifies the directory in which to run the discovered test cases.  If this
+    option is not provided, the current binary directory is used.
+
+  ``TEST_PREFIX prefix``
+    Specifies a ``prefix`` to be prepended to the name of each discovered test
+    case.  This can be useful when the same test executable is being used in
+    multiple calls to ``catch_discover_tests()`` but with different
+    ``TEST_SPEC`` or ``EXTRA_ARGS``.
+
+  ``TEST_SUFFIX suffix``
+    Similar to ``TEST_PREFIX`` except the ``suffix`` is appended to the name of
+    every discovered test case.  Both ``TEST_PREFIX`` and ``TEST_SUFFIX`` may
+    be specified.
+
+  ``PROPERTIES name1 value1...``
+    Specifies additional properties to be set on all tests discovered by this
+    invocation of ``catch_discover_tests``.
+
+  ``TEST_LIST var``
+    Make the list of tests available in the variable ``var``, rather than the
+    default ``<target>_TESTS``.  This can be useful when the same test
+    executable is being used in multiple calls to ``catch_discover_tests()``.
+    Note that this variable is only available in CTest.

+Find the OpenGL Extension Wrangler Library (GLEW)
+
+Input Variables
+^^^^^^^^^^^^^^^
+
+The following variables may be set to influence this module’s behavior:
+
+``GLEW_USE_STATIC_LIBS``
+  to find and create :prop_tgt:`IMPORTED` target for static linkage.
+
+``GLEW_VERBOSE``
+  to output a detailed log of this module.
+
+Imported Targets
+^^^^^^^^^^^^^^^^
+
+This module defines the following :ref:`Imported Targets <Imported Targets>`:
+
+
+``GLEW::glew``
+  The GLEW shared library.
+``GLEW::glew_s``
+  The GLEW static library, if ``GLEW_USE_STATIC_LIBS`` is set to ``TRUE``.
+``GLEW::GLEW``
+  Duplicates either ``GLEW::glew`` or ``GLEW::glew_s`` based on availability.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module defines the following variables:
+
+``GLEW_INCLUDE_DIRS``
+  include directories for GLEW
+``GLEW_LIBRARIES``
+  libraries to link against GLEW
+``GLEW_SHARED_LIBRARIES``
+  libraries to link against shared GLEW
+``GLEW_STATIC_LIBRARIES``
+  libraries to link against static GLEW
+``GLEW_FOUND``
+  true if GLEW has been found and can be used
+``GLEW_VERSION``
+  GLEW version
+``GLEW_VERSION_MAJOR``
+  GLEW major version
+``GLEW_VERSION_MINOR``
+  GLEW minor version
+``GLEW_VERSION_MICRO``

+FindOpenVDB
+-----------
+
+Find OpenVDB include dirs, libraries and settings
+
+Use this module by invoking find_package with the form::
+
+  find_package(OpenVDB
+    [version] [EXACT]      # Minimum or EXACT version
+    [REQUIRED]             # Fail with error if OpenVDB is not found
+    [COMPONENTS <libs>...] # OpenVDB libraries by their canonical name
+                           # e.g. "openvdb" for "libopenvdb"
+    )
+
+IMPORTED Targets
+^^^^^^^^^^^^^^^^
+
+``OpenVDB::openvdb``
+  The core openvdb library target.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This will define the following variables:
+
+``OpenVDB_FOUND``
+  True if the system has the OpenVDB library.
+``OpenVDB_VERSION``
+  The version of the OpenVDB library which was found.
+``OpenVDB_INCLUDE_DIRS``
+  Include directories needed to use OpenVDB.
+``OpenVDB_LIBRARIES``
+  Libraries needed to link to OpenVDB.
+``OpenVDB_LIBRARY_DIRS``
+  OpenVDB library directories.
+``OpenVDB_DEFINITIONS``
+  Definitions to use when compiling code that uses OpenVDB.
+``OpenVDB_{COMPONENT}_FOUND``
+  True if the system has the named OpenVDB component.
+``OpenVDB_USES_BLOSC``
+  True if the OpenVDB Library has been built with blosc support
+``OpenVDB_USES_LOG4CPLUS``
+  True if the OpenVDB Library has been built with log4cplus support
+``OpenVDB_USES_EXR``
+  True if the OpenVDB Library has been built with openexr support
+``OpenVDB_ABI``
+  Set if this module was able to determine the ABI number the located
+  OpenVDB Library was built against. Unset otherwise.
+
+Cache Variables
+^^^^^^^^^^^^^^^
+
+The following cache variables may also be set:
+
+``OpenVDB_INCLUDE_DIR``
+  The directory containing ``openvdb/version.h``.
+``OpenVDB_{COMPONENT}_LIBRARY``
+  Individual component libraries for OpenVDB
+
+Hints
+^^^^^
+
+Instead of explicitly setting the cache variables, the following variables
+may be provided to tell this module where to look.
+
+``OPENVDB_ROOT``
+  Preferred installation prefix.
+``OPENVDB_INCLUDEDIR``
+  Preferred include directory e.g. <prefix>/include
+``OPENVDB_LIBRARYDIR``
+  Preferred library directory e.g. <prefix>/lib
+``SYSTEM_LIBRARY_PATHS``
+  Paths appended to all include and lib searches.

+FindPackageHandleStandardArgs
+-----------------------------
+
+This module provides a function intended to be used in :ref:`Find Modules`
+implementing :command:`find_package(<PackageName>)` calls.  It handles the
+``REQUIRED``, ``QUIET`` and version-related arguments of ``find_package``.
+It also sets the ``<PackageName>_FOUND`` variable.  The package is
+considered found if all variables listed contain valid results, e.g.
+valid filepaths.
+
+.. command:: find_package_handle_standard_args
+
+  There are two signatures::
+
+    find_package_handle_standard_args(<PackageName>
+      (DEFAULT_MSG|<custom-failure-message>)
+      <required-var>...
+      )
+
+    find_package_handle_standard_args(<PackageName>
+      [FOUND_VAR <result-var>]
+      [REQUIRED_VARS <required-var>...]
+      [VERSION_VAR <version-var>]
+      [HANDLE_COMPONENTS]
+      [CONFIG_MODE]
+      [FAIL_MESSAGE <custom-failure-message>]
+      )
+
+  The ``<PackageName>_FOUND`` variable will be set to ``TRUE`` if all
+  the variables ``<required-var>...`` are valid and any optional
+  constraints are satisfied, and ``FALSE`` otherwise.  A success or
+  failure message may be displayed based on the results and on
+  whether the ``REQUIRED`` and/or ``QUIET`` option was given to
+  the :command:`find_package` call.
+
+  The options are:
+
+  ``(DEFAULT_MSG|<custom-failure-message>)``
+    In the simple signature this specifies the failure message.
+    Use ``DEFAULT_MSG`` to ask for a default message to be computed
+    (recommended).  Not valid in the full signature.
+
+  ``FOUND_VAR <result-var>``
+    Obsolete.  Specifies either ``<PackageName>_FOUND`` or
+    ``<PACKAGENAME>_FOUND`` as the result variable.  This exists only
+    for compatibility with older versions of CMake and is now ignored.
+    Result variables of both names are always set for compatibility.
+
+  ``REQUIRED_VARS <required-var>...``
+    Specify the variables which are required for this package.
+    These may be named in the generated failure message asking the
+    user to set the missing variable values.  Therefore these should
+    typically be cache entries such as ``FOO_LIBRARY`` and not output
+    variables like ``FOO_LIBRARIES``.
+
+  ``VERSION_VAR <version-var>``
+    Specify the name of a variable that holds the version of the package
+    that has been found.  This version will be checked against the
+    (potentially) specified required version given to the
+    :command:`find_package` call, including its ``EXACT`` option.
+    The default messages include information about the required
+    version and the version which has been actually found, both
+    if the version is ok or not.
+
+  ``HANDLE_COMPONENTS``
+    Enable handling of package components.  In this case, the command
+    will report which components have been found and which are missing,
+    and the ``<PackageName>_FOUND`` variable will be set to ``FALSE``
+    if any of the required components (i.e. not the ones listed after
+    the ``OPTIONAL_COMPONENTS`` option of :command:`find_package`) are
+    missing.
+
+  ``CONFIG_MODE``
+    Specify that the calling find module is a wrapper around a
+    call to ``find_package(<PackageName> NO_MODULE)``.  This implies
+    a ``VERSION_VAR`` value of ``<PackageName>_VERSION``.  The command
+    will automatically check whether the package configuration file
+    was found.
+
+  ``FAIL_MESSAGE <custom-failure-message>``
+    Specify a custom failure message instead of using the default
+    generated message.  Not recommended.
+
+Example for the simple signature:
+
+.. code-block:: cmake
+
+  find_package_handle_standard_args(LibXml2 DEFAULT_MSG
+    LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)
+
+The ``LibXml2`` package is considered to be found if both
+``LIBXML2_LIBRARY`` and ``LIBXML2_INCLUDE_DIR`` are valid.
+Then also ``LibXml2_FOUND`` is set to ``TRUE``.  If it is not found
+and ``REQUIRED`` was used, it fails with a
+:command:`message(FATAL_ERROR)`, independent whether ``QUIET`` was
+used or not.  If it is found, success will be reported, including
+the content of the first ``<required-var>``.  On repeated CMake runs,
+the same message will not be printed again.
+
+Example for the full signature:
+
+.. code-block:: cmake
+
+  find_package_handle_standard_args(LibArchive
+    REQUIRED_VARS LibArchive_LIBRARY LibArchive_INCLUDE_DIR
+    VERSION_VAR LibArchive_VERSION)
+
+In this case, the ``LibArchive`` package is considered to be found if
+both ``LibArchive_LIBRARY`` and ``LibArchive_INCLUDE_DIR`` are valid.
+Also the version of ``LibArchive`` will be checked by using the version
+contained in ``LibArchive_VERSION``.  Since no ``FAIL_MESSAGE`` is given,
+the default messages will be printed.
+
+Another example for the full signature:
+
+.. code-block:: cmake
+
+  find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
+  find_package_handle_standard_args(Automoc4  CONFIG_MODE)
+
+In this case, a ``FindAutmoc4.cmake`` module wraps a call to
+``find_package(Automoc4 NO_MODULE)`` and adds an additional search
+directory for ``automoc4``.  Then the call to
+``find_package_handle_standard_args`` produces a proper success/failure
+message.

+# FindTBB
+# -------
+#
+# Find TBB include directories and libraries.
+#
+# Usage:
+#
+#  find_package(TBB [major[.minor]] [EXACT]
+#               [QUIET] [REQUIRED]
+#               [[COMPONENTS] [components...]]
+#               [OPTIONAL_COMPONENTS components...]) 
+#
+# where the allowed components are tbbmalloc and tbb_preview. Users may modify 
+# the behavior of this module with the following variables:
+#
+# * TBB_ROOT_DIR          - The base directory the of TBB installation.
+# * TBB_INCLUDE_DIR       - The directory that contains the TBB headers files.
+# * TBB_LIBRARY           - The directory that contains the TBB library files.
+# * TBB_<library>_LIBRARY - The path of the TBB the corresponding TBB library. 
+#                           These libraries, if specified, override the 
+#                           corresponding library search results, where <library>
+#                           may be tbb, tbb_debug, tbbmalloc, tbbmalloc_debug,
+#                           tbb_preview, or tbb_preview_debug.
+# * TBB_USE_DEBUG_BUILD   - The debug version of tbb libraries, if present, will
+#                           be used instead of the release version.
+# * TBB_STATIC            - Static linking of libraries with a _static suffix.
+#                           For example, on Windows a tbb_static.lib will be searched for
+#                           instead of tbb.lib.
+#
+# Users may modify the behavior of this module with the following environment
+# variables:
+#
+# * TBB_INSTALL_DIR 
+# * TBBROOT
+# * LIBRARY_PATH
+#
+# This module will set the following variables:
+#
+# * TBB_FOUND             - Set to false, or undefined, if we haven’t found, or
+#                           don’t want to use TBB.
+# * TBB_<component>_FOUND - If False, optional <component> part of TBB sytem is
+#                           not available.
+# * TBB_VERSION           - The full version string
+# * TBB_VERSION_MAJOR     - The major version
+# * TBB_VERSION_MINOR     - The minor version
+# * TBB_INTERFACE_VERSION - The interface version number defined in 
+#                           tbb/tbb_stddef.h.
+# * TBB_<library>_LIBRARY_RELEASE - The path of the TBB release version of 
+#                           <library>, where <library> may be tbb, tbb_debug,
+#                           tbbmalloc, tbbmalloc_debug, tbb_preview, or 
+#                           tbb_preview_debug.
+# * TBB_<library>_LIBRARY_DEGUG - The path of the TBB release version of 
+#                           <library>, where <library> may be tbb, tbb_debug,
+#                           tbbmalloc, tbbmalloc_debug, tbb_preview, or 
+#                           tbb_preview_debug.
+#
+# The following varibles should be used to build and link with TBB:
+#
+# * TBB_INCLUDE_DIRS        - The include directory for TBB.
+# * TBB_LIBRARIES           - The libraries to link against to use TBB.
+# * TBB_LIBRARIES_RELEASE   - The release libraries to link against to use TBB.
+# * TBB_LIBRARIES_DEBUG     - The debug libraries to link against to use TBB.
+# * TBB_DEFINITIONS         - Definitions to use when compiling code that uses
+#                             TBB.
+# * TBB_DEFINITIONS_RELEASE - Definitions to use when compiling release code that
+#                             uses TBB.
+# * TBB_DEFINITIONS_DEBUG   - Definitions to use when compiling debug code that
+#                             uses TBB.
+#
+# This module will also create the "tbb" target that may be used when building
+# executables and libraries.

+------------------
+
+A utility CMake file which provides helper functions for configuring an
+OpenVDB installation.
+
+Use this module by invoking include with the form::
+
+  include ( OpenVDBUtils )
+
+
+The following functions are provided:
+
+``OPENVDB_VERSION_FROM_HEADER``
+
+  OPENVDB_VERSION_FROM_HEADER ( <header_path>
+    VERSION [<version>]
+    MAJOR   [<version>]
+    MINOR   [<version>]
+    PATCH   [<version>] )
+
+  Parse the provided version file to retrieve the current OpenVDB
+  version information. The file is expected to be a version.h file
+  as found in the following path of an OpenVDB repository:
+    openvdb/version.h
+
+  If the file does not exist, variables are unmodified.
+
+``OPENVDB_ABI_VERSION_FROM_PRINT``
+
+  OPENVDB_ABI_VERSION_FROM_PRINT ( <vdb_print>
+    [QUIET]
+    ABI [<version>] )
+
+  Retrieve the ABI version that an installation of OpenVDB was compiled
+  for using the provided vdb_print binary. Parses the result of:
+    vdb_print --version
+
+  If the binary does not exist or fails to launch, variables are
+  unmodified.

+#   SOURCE_C/CXX: Specifies the .c/.cpp source file that includes

+# Caveats:
+#
+#   * Its not currently possible to use the same precompiled-header in
+#     more than a single target in the same directory (No way to set
+#     the source file properties differently for each target).

+# This CMake project downloads, configures and builds QIDIStudio dependencies on Unix and Windows.
+#
+# When using this script, it's recommended to perform an out-of-source build using CMake.
+#
+# All the dependencies are installed in a `destdir` directory in the root of the build directory,
+# in a traditional Unix-style prefix structure. The destdir can be used directly by CMake
+# when building QIDIStudio - to do this, set the CMAKE_PREFIX_PATH to ${destdir}/usr/local.
+# Warning: On UNIX/Linux, you also need to set -DSLIC3R_STATIC=1 when building QIDIStudio.
+#
+# For better clarity of console output, it's recommended to _not_ use a parallelized build
+# for the top-level command, ie. use `make -j 1` or `ninja -j 1` to force single-threaded top-level
+# build. This doesn't degrade performance as individual dependencies are built in parallel fashion
+# if supported by the dependency.
+#
+# On Windows, architecture (64 vs 32 bits) is judged based on the compiler variant.
+# To build dependencies for either 64 or 32 bit OS, use the respective compiler command line.
+#
+# WARNING: On UNIX platforms wxWidgets hardcode the destdir path into its `wx-conffig` utility,
+# therefore, unfortunatelly, the installation cannot be copied/moved elsewhere without re-installing wxWidgets.

+macro(expat_shy_set var default cache type desc)
+    # Macro expat_shy_set came into life because:
+    # - Expat was previously using an inconsistent mix of CMake's native set()
+    #   and option() to define public build time options.
+    # - option() is more friendly than set() with regard to configuring an
+    #   external project that is pulled in by means of add_subdirectory() --
+    #   see comments in issue #597 -- so we wanted to get away from set().
+    # - option() auto-converts non-bool values to bool when writing to the CMake
+    #   cache, so we needed something that supports non-bool better and hence
+    #   wanted to get away from plain option(), too.
+    #
+    # As a result, this function serves as a hybrid between CMake's regular set()
+    # and option(): from set() it takes support for non-bool types and the function
+    # name and signature whereas from option() (with policy CMP0077 mode NEW) it
+    # takes being shy when a value has previously been defined for that variable.

+# Expat, Release 2.5.0
+
+This is Expat, a C library for parsing XML, started by
+[James Clark](https://en.wikipedia.org/wiki/James_Clark_%28programmer%29) in 1997.
+Expat is a stream-oriented XML parser.  This means that you register
+handlers with the parser before starting the parse.  These handlers
+are called when the parser discovers the associated structures in the
+document being parsed.  A start tag is an example of the kind of
+structures for which you may register handlers.
+
+Expat supports the following compilers:
+
+- GNU GCC >=4.5
+- LLVM Clang >=3.5
+- Microsoft Visual Studio >=15.0/2017 (rolling `${today} minus 5 years`)
+
+Windows users can use the
+[`expat-win32bin-*.*.*.{exe,zip}` download](https://github.com/libexpat/libexpat/releases),
+which includes both pre-compiled libraries and executables, and source code for
+developers.
+
+Expat is [free software](https://www.gnu.org/philosophy/free-sw.en.html).
+You may copy, distribute, and modify it under the terms of the License
+contained in the file

+
+
+## Using libexpat in your CMake-Based Project
+
+There are two ways of using libexpat with CMake:
+
+### a) Module Mode
+
+This approach leverages CMake's own [module `FindEXPAT`](https://cmake.org/cmake/help/latest/module/FindEXPAT.html).
+
+Notice the *uppercase* `EXPAT` in the following example:
+
+```cmake
+cmake_minimum_required(VERSION 3.0)  # or 3.10, see below
+
+project(hello VERSION 1.0.0)
+
+find_package(EXPAT 2.2.8 MODULE REQUIRED)
+
+add_executable(hello
+    hello.c
+)
+
+# a) for CMake >=3.10 (see CMake's FindEXPAT docs)
+target_link_libraries(hello PUBLIC EXPAT::EXPAT)
+
+# b) for CMake >=3.0
+target_include_directories(hello PRIVATE ${EXPAT_INCLUDE_DIRS})
+target_link_libraries(hello PUBLIC ${EXPAT_LIBRARIES})
+```
+
+### b) Config Mode
+
+This approach requires files from…
+
+- libexpat >=2.2.8 where packaging uses the CMake build system
+or
+- libexpat >=2.3.0 where packaging uses the GNU Autotools build system
+  on Linux
+or
+- libexpat >=2.4.0 where packaging uses the GNU Autotools build system
+  on macOS or MinGW.
+
+Notice the *lowercase* `expat` in the following example:
+
+```cmake
+cmake_minimum_required(VERSION 3.0)
+
+project(hello VERSION 1.0.0)
+
+find_package(expat 2.2.8 CONFIG REQUIRED char dtd ns)
+
+add_executable(hello
+    hello.c
+)
+
+target_link_libraries(hello PUBLIC expat::expat)
+```
+
+
+## Building from a Git Clone
+
+If you are building Expat from a check-out from the
+[Git repository](https://github.com/libexpat/libexpat/),
+you need to run a script that generates the configure script using the
+GNU autoconf and libtool tools.  To do this, you need to have
+autoconf 2.58 or newer. Run the script like this:
+
+```console
+./buildconf.sh
+```
+
+Once this has been done, follow the same instructions as for building
+from a source distribution.
+
+
+## Building from a Source Distribution
+
+### a) Building with the configure script (i.e. GNU Autotools)
+
+To build Expat from a source distribution, you first run the
+configuration shell script in the top level distribution directory:
+
+```console
+./configure
+```
+
+There are many options which you may provide to configure (which you
+can discover by running configure with the `--help` option).  But the
+one of most interest is the one that sets the installation directory.
+By default, the configure script will set things up to install
+libexpat into `/usr/local/lib`, `expat.h` into `/usr/local/include`, and
+`xmlwf` into `/usr/local/bin`.  If, for example, you'd prefer to install
+into `/home/me/mystuff/lib`, `/home/me/mystuff/include`, and
+`/home/me/mystuff/bin`, you can tell `configure` about that with:
+
+```console
+./configure --prefix=/home/me/mystuff
+```
+
+Another interesting option is to enable 64-bit integer support for
+line and column numbers and the over-all byte index:
+
+```console
+./configure CPPFLAGS=-DXML_LARGE_SIZE
+```
+
+However, such a modification would be a breaking change to the ABI
+and is therefore not recommended for general use — e.g. as part of
+a Linux distribution — but rather for builds with special requirements.
+
+After running the configure script, the `make` command will build
+things and `make install` will install things into their proper
+location.  Have a look at the `Makefile` to learn about additional
+`make` options.  Note that you need to have write permission into
+the directories into which things will be installed.
+
+If you are interested in building Expat to provide document
+information in UTF-16 encoding rather than the default UTF-8, follow
+these instructions (after having run `make distclean`).
+Please note that we configure with `--without-xmlwf` as xmlwf does not
+support this mode of compilation (yet):
+
+1. Mass-patch `Makefile.am` files to use `libexpatw.la` for a library name:
+   <br/>
+   `find -name Makefile.am -exec sed
+       -e 's,libexpat\.la,libexpatw.la,'
+       -e 's,libexpat_la,libexpatw_la,'
+       -i {} +`
+
+1. Run `automake` to re-write `Makefile.in` files:<br/>
+   `automake`
+
+1. For UTF-16 output as unsigned short (and version/error strings as char),
+   run:<br/>
+   `./configure CPPFLAGS=-DXML_UNICODE --without-xmlwf`<br/>
+   For UTF-16 output as `wchar_t` (incl. version/error strings), run:<br/>
+   `./configure CFLAGS="-g -O2 -fshort-wchar" CPPFLAGS=-DXML_UNICODE_WCHAR_T
+       --without-xmlwf`
+   <br/>Note: The latter requires libc compiled with `-fshort-wchar`, as well.
+
+1. Run `make` (which excludes xmlwf).
+
+1. Run `make install` (again, excludes xmlwf).
+
+Using `DESTDIR` is supported.  It works as follows:
+
+```console
+make install DESTDIR=/path/to/image
+```
+
+overrides the in-makefile set `DESTDIR`, because variable-setting priority is
+
+1. commandline
+1. in-makefile
+1. environment
+
+Note: This only applies to the Expat library itself, building UTF-16 versions
+of xmlwf and the tests is currently not supported.
+
+When using Expat with a project using autoconf for configuration, you
+can use the probing macro in `conftools/expat.m4` to determine how to
+include Expat.  See the comments at the top of that file for more
+information.
+
+A reference manual is available in the file `doc/reference.html` in this
+distribution.
+
+
+### b) Building with CMake
+
+The CMake build system is still *experimental* and may replace the primary
+build system based on GNU Autotools at some point when it is ready.
+
+
+#### Available Options
+
+For an idea of the available (non-advanced) options for building with CMake:
+
+```console
+# rm -f CMakeCache.txt ; cmake -D_EXPAT_HELP=ON -LH . | grep -B1 ':.*=' | sed 's,^--$,,'
+// Choose the type of build, options are: None Debug Release RelWithDebInfo MinSizeRel ...
+CMAKE_BUILD_TYPE:STRING=
+
+// Install path prefix, prepended onto install directories.
+CMAKE_INSTALL_PREFIX:PATH=/usr/local
+
+// Path to a program.
+DOCBOOK_TO_MAN:FILEPATH=/usr/bin/docbook2x-man
+
+// Build man page for xmlwf

+
+   XMLCALL    - The calling convention to use for all calls across the

+

+                (.dll, .so, or .sl, depending on your platform).
+
+   The XMLCALL macro was added in Expat 1.95.7.  The only one which is
+   expected to be directly useful in client code is XMLCALL.
+

+/* internal.h
+
+   Internal definitions used by Expat.  This is not needed to compile
+   client code.
+
+   The following calling convention macros are defined for frequently
+   called functions:
+
+   FASTCALL    - Used for those internal functions that have a simple
+                 body and a low number of arguments and local variables.
+
+   PTRCALL     - Used for functions called though function pointers.
+
+   PTRFASTCALL - Like PTRCALL, but for low number of arguments.
+
+   inline      - Used for selected internal functions for which inlining
+                 may improve performance on some platforms.
+
+   Note: Use of these macros is based on judgement, not hard rules,
+         and therefore subject to change.

+ *   - Re-format code using clang-format 9
+ *
+ * 2018-07-08  (Anton Maklakov)
+ *   - Add "fall through" markers for GCC's -Wimplicit-fallthrough
+ *
+ * 2017-11-03  (Sebastian Pipping)
+ *   - Hide sip_tobin and sip_binof unless SIPHASH_TOBIN macro is defined
+ *
+ * 2017-07-25  (Vadim Zeitlin)
+ *   - Fix use of SIPHASH_MAIN macro
+ *
+ * 2017-07-05  (Sebastian Pipping)
+ *   - Use _SIP_ULL macro to not require a C++11 compiler if compiled as C++
+ *   - Add const qualifiers at two places

+ * 2017-06-18  (Sebastian Pipping)
+ *   - Clarify license note in the header
+ *   - Address C89 issues:
+ *     - Stop using inline keyword (and let compiler decide)
+ *     - Replace _Bool by int
+ *     - Turn macro siphash24 into a function
+ *     - Address invalid conversion (void pointer) by explicit cast
+ *   - Address lack of stdint.h for Visual Studio 2003 to 2008
+ *   - Always expose sip24_valid (for self-tests)
+ *
+ * 2012-11-04 - Born.  (William Ahern)
+ * --------------------------------------------------------------------------
+ * USAGE:
+ *
+ * SipHash-2-4 takes as input two 64-bit words as the key, some number of
+ * message bytes, and outputs a 64-bit word as the message digest. This
+ * implementation employs two data structures: a struct sipkey for
+ * representing the key, and a struct siphash for representing the hash
+ * state.
+ *
+ * For converting a 16-byte unsigned char array to a key, use either the
+ * macro sip_keyof or the routine sip_tokey. The former instantiates a
+ * compound literal key, while the latter requires a key object as a
+ * parameter.
+ *
+ * 	unsigned char secret[16];
+ * 	arc4random_buf(secret, sizeof secret);
+ * 	struct sipkey *key = sip_keyof(secret);
+ *
+ * For hashing a message, use either the convenience macro siphash24 or the
+ * routines sip24_init, sip24_update, and sip24_final.
+ *
+ * 	struct siphash state;
+ * 	void *msg;
+ * 	size_t len;
+ * 	uint64_t hash;
+ *
+ * 	sip24_init(&state, key);
+ * 	sip24_update(&state, msg, len);
+ * 	hash = sip24_final(&state);
+ *
+ * or
+ *
+ * 	hash = siphash24(msg, len, key);
+ *
+ * To convert the 64-bit hash value to a canonical 8-byte little-endian
+ * binary representation, use either the macro sip_binof or the routine
+ * sip_tobin. The former instantiates and returns a compound literal array,
+ * while the latter requires an array object as a parameter.
+ * --------------------------------------------------------------------------
+ * NOTES:
+ *
+ * o Neither sip_keyof, sip_binof, nor siphash24 will work with compilers
+ *   lacking compound literal support. Instead, you must use the lower-level
+ *   interfaces which take as parameters the temporary state objects.
+ *
+ * o Uppercase macros may evaluate parameters more than once. Lowercase
+ *   macros should not exhibit any such side effects.

+# GLEW - The OpenGL Extension Wrangler Library
+
+The OpenGL Extension Wrangler Library (GLEW) is a cross-platform open-source C/C++ extension loading library. GLEW provides efficient run-time mechanisms for determining which OpenGL extensions are supported on the target platform. OpenGL core and extension functionality is exposed in a single header file. GLEW has been tested on a variety of operating systems, including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris.

+
+## Build
+
+It is highly recommended to build from a tgz or zip release snapshot.
+The code generation workflow is a complex brew of gnu make, perl and python, that works best on Linux or Mac.
+The code generation is known to work on Windows using [MSYS2](https://www.msys2.org/).
+For most end-users of GLEW the official releases are the best choice, with first class support.
+
+### Linux and Mac
+
+#### Using GNU Make
+
+GNU make is the primary build system for GLEW, historically.
+It includes targets for building the sources and headers, for maintenance purposes.
+
+##### Install build tools
+
+Debian/Ubuntu/Mint:    `$ sudo apt-get install build-essential libxmu-dev libxi-dev libgl-dev`
+
+RedHat/CentOS/Fedora:  `$ sudo yum install libXmu-devel libXi-devel libGL-devel`
+
+FreeBSD: `# pkg install xorg lang/gcc git cmake gmake bash python perl5`
+
+##### Build
+
+	$ make
+	$ sudo make install
+	$ make clean
+
+Targets:    `all, glew.lib (sub-targets: glew.lib.shared, glew.lib.static), glew.bin, clean, install, uninstall`
+
+Variables:  `SYSTEM=linux-clang, GLEW_DEST=/usr/local, STRIP=`
+
+_Note: you may need to call `make` in the  **auto** folder first_
+
+##### Linux EGL
+
+	$ sudo apt install libegl1-mesa-dev
+	$ make SYSTEM=linux-egl
+
+##### Linux OSMesa
+
+	$ sudo apt install libosmesa-dev
+	$ make SYSTEM=linux-osmesa
+
+##### Linux mingw-w64
+
+	$ sudo apt install mingw-w64
+	$ make SYSTEM=linux-mingw32
+	$ make SYSTEM=linux-mingw64
+
+#### Using cmake
+
+The cmake build is mostly contributer maintained.
+Due to the multitude of use cases this is maintained on a _best effort_ basis.
+Pull requests are welcome.
+
+*CMake 2.8.12 or higher is required.*
+
+##### Install build tools
+
+Debian/Ubuntu/Mint:   `$ sudo apt-get install build-essential libxmu-dev libxi-dev libgl-dev cmake git`
+
+RedHat/CentOS/Fedora: `$ sudo yum install libXmu-devel libXi-devel libGL-devel cmake git`
+
+##### Build
+
+	$ cd build
+	$ cmake ./cmake
+	$ make -j4

+## Code Generation
+
+A Unix or Mac environment is needed for building GLEW from scratch to
+include new extensions, or customize the code generation. The extension
+data is regenerated from the top level source directory with:
+
+	make extensions
+
+An alternative to generating the GLEW sources from scratch is to
+download a pre-generated (unsupported) snapshot:
+
+https://sourceforge.net/projects/glew/files/glew/snapshots/
+
+## Authors
+
+GLEW is currently maintained by [Nigel Stewart](https://github.com/nigels-com)
+with bug fixes, new OpenGL extension support and new releases.
+
+GLEW was developed by [Milan Ikits](http://www.cs.utah.edu/~ikits/)
+and [Marcelo Magallon](http://wwwvis.informatik.uni-stuttgart.de/~magallon/).
+Aaron Lefohn, Joe Kniss, and Chris Wyman were the first users and also
+assisted with the design and debugging process.
+
+The acronym GLEW originates from Aaron Lefohn.
+Pasi Kärkkäinen identified and fixed several problems with
+GLX and SDL.  Nate Robins created the `wglinfo` utility, to
+which modifications were made by Michael Wimmer.
+
+## Contributions
+
+GLEW welcomes community contributions.  Typically these are co-ordinated
+via [Issues](https://github.com/nigels-com/glew/issues) or
+[Pull Requests](https://github.com/nigels-com/glew/pulls) in the
+GitHub web interface.
+
+Be sure to mention platform and compiler toolchain details when filing
+a bug report.  The output of `glewinfo` can be quite useful for discussion
+also.
+
+Generally GLEW is usually released once a year, around the time of the Siggraph
+computer graphics conference.  If you're not using the current release
+version of GLEW, be sure to check if the issue or bug is fixed there.

+                    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) <year>  <name of author>
+
+    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:
+
+    <program>  Copyright (C) <year>  <name of author>
+    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

+
+			THE GNU MP LIBRARY
+
+
+GNU MP is a library for arbitrary precision arithmetic, operating on signed
+integers, rational numbers, and floating point numbers.  It has a rich set of
+functions, and the functions have a regular interface.
+
+GNU MP is designed to be as fast as possible, both for small operands and huge
+operands.  The speed is achieved by using fullwords as the basic arithmetic
+type, by using fast algorithms, with carefully optimized assembly code for the
+most common inner loops for lots of CPUs, and by a general emphasis on speed
+(instead of simplicity or elegance).
+
+GNU MP is believed to be faster than any other similar library.  Its advantage
+increases with operand sizes for certain operations, since GNU MP in many
+cases has asymptotically faster algorithms.
+
+GNU MP is free software and may be freely copied on the terms contained in the
+files COPYING.LIB and COPYING (most of GNU MP is under the former, some under
+the latter).
+
+
+
+			OVERVIEW OF GNU MP
+
+There are five classes of functions in GNU MP.
+
+ 1. Signed integer arithmetic functions (mpz).  These functions are intended
+    to be easy to use, with their regular interface.  The associated type is
+    `mpz_t'.
+
+ 2. Rational arithmetic functions (mpq).  For now, just a small set of
+    functions necessary for basic rational arithmetics.  The associated type
+    is `mpq_t'.
+
+ 3. Floating-point arithmetic functions (mpf).  If the C type `double'
+    doesn't give enough precision for your application, declare your
+    variables as `mpf_t' instead, set the precision to any number desired,
+    and call the functions in the mpf class for the arithmetic operations.
+
+ 4. Positive-integer, hard-to-use, very low overhead functions are in the
+    mpn class.  No memory management is performed.  The caller must ensure
+    enough space is available for the results.  The set of functions is not
+    regular, nor is the calling interface.  These functions accept input
+    arguments in the form of pairs consisting of a pointer to the least
+    significant word, and an integral size telling how many limbs (= words)
+    the pointer points to.
+
+    Almost all calculations, in the entire package, are made by calling these
+    low-level functions.
+
+ 5. Berkeley MP compatible functions.
+
+    To use these functions, include the file "mp.h".  You can test if you are
+    using the GNU version by testing if the symbol __GNU_MP__ is defined.
+
+For more information on how to use GNU MP, please refer to the documentation.
+It is composed from the file doc/gmp.texi, and can be displayed on the screen
+or printed.  How to do that, as well how to build the library, is described in
+the INSTALL file in this directory.
+
+
+
+			REPORTING BUGS
+
+If you find a bug in the library, please make sure to tell us about it!
+
+You should first check the GNU MP web pages at http://gmplib.org/, under
+"Status of the current release".  There will be patches for all known serious
+bugs there.
+
+Report bugs to gmp-bugs@gmplib.org.  What information is needed in a useful bug
+report is described in the manual.  The same address can be used for suggesting
+modifications and enhancements.
