+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 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.

+# * 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

+#                           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.

+# * 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

+OpenVDBUtils.cmake
+------------------
+
+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.

+#
+#   add_precompiled_header(target pchheader.h

+#       [SOURCE_C pchheader.c]
+#       [SOURCE_CXX pchheader.cpp])
+#
+# Options:
+#
+#   FORCEINCLUDE: Add compiler flags to automatically include the
+#   pchheader.h from every source file. Works with both GCC and
+#   MSVC. This is recommended.
+#
+#   SOURCE_C/CXX: Specifies the .c/.cpp source file that includes
+#   pchheader.h for generating the pre-compiled header
+#   output. Defaults to pchheader.c. Only required for MSVC.
+#
+# 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).
+#
+#   * MSVC: A source file with the same name as the header must exist
+#     and be included in the target (E.g. header.cpp). Name of file
+#     can be changed using the SOURCE_CXX/SOURCE_C options.

+# This CMake project downloads, configures and builds QIDISlicer 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 QIDISlicer - 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 QIDISlicer.
+#
+# 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.

+                       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.

+                    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
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

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

+# Dependency report for QIDISlicer
+## Possible dynamic linking on Linux
+* zlib: Strict dependency required from the system, linked dynamically. Many other libs depend on zlib.
+* wxWidgets: searches for wx-3.1 by default, but with cmake option `SLIC3R_WX_STABLE=ON` it will use wx-3.0 bundled with most distros.
+* libcurl
+* tbb
+* boost
+* eigen
+* glew
+* expat
+* openssl
+* nlopt
+* openvdb: This library depends on other libs, namely boost, zlib, openexr, blosc (not strictly), etc... 
+* CGAL: Needs additional dependencies
+    * MPFR 
+    * GMP
+
+## External libraries in source tree
+* ad-mesh: Lots of customization, have to be bundled in the source tree.
+* avrdude: Like ad-mesh, many customization, need to be in the source tree.
+* clipper: An important library we have to have full control over it. We also have some slicer specific modifications.
+* glu-libtess: This is an extract of the mesa/glu library not officially available as a package.
+* imgui: no packages for debian, author suggests using in the source tree
+* miniz: No packages, author suggests using in the source tree
+* qhull: libqhull-dev does not contain libqhullcpp => link errors. Until it is fixed, we will use the builtin version. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=925540
+* semver: One module C library, author expects to use clib for installation. No packages.

+# Building QIDISlicer on UNIX/Linux
+
+Please understand that QIDISlicer team cannot support compilation on all possible Linux distros. Namely, we cannot help troubleshoot OpenGL driver issues or dependency issues if compiled against distro provided libraries. **We can only support QIDISlicer statically linked against the dependencies compiled with the `deps` scripts**, the same way we compile QIDISlicer for our [binary builds](https://github.com/qidi3d/QIDISlicer/releases).
+
+If you have some reason to link dynamically to your system libraries, you are free to do so, but we can not and will not troubleshoot any issues you possibly run into.
+
+Instead of compiling QIDISlicer from source code, one may also consider to install QIDISlicer [pre-compiled by contributors](https://github.com/qidi3d/QIDISlicer/wiki/QIDISlicer-on-Linux---binary-distributions).
+
+## Step by step guide
+
+This guide describes building QIDISlicer statically against dependencies pulled by our `deps` script. Running all the listed commands in order should result in successful build.
+
+#### 0. Prerequisities
+
+You need at least 8GB of RAM on your system. Linking on a 4GB RAM system will likely fail and you may need to limit the number of compiler processes with the '-j xxx' make or ninja parameter, where 'xxx' is the number of compiler processes launched if running on low RAM multi core system, for example on Raspberry PI.
+
+GNU build tools, CMake, git and other libraries have to be installed on the build machine.
+Unless that's already the case, install them as usual from your distribution packages.
+E.g. on Ubuntu 20.10, run
+```shell
+sudo apt-get install  -y \
+git \
+build-essential \
+autoconf \
+cmake \
+libglu1-mesa-dev \
+libgtk-3-dev \
+libdbus-1-dev \
+
+```
+The names of the packages may be different on different distros.
+
+#### 1. Cloning the repository
+
+
+Cloning the repository is simple thanks to git and Github. Simply `cd` into wherever you want to clone QIDISlicer code base and run
+```
+git clone https://www.github.com/qidi3d/QIDISlicer
+cd QIDISlicer
+```
+This will download the source code into a new directory and `cd` into it. You can now optionally select a tag/branch/commit to build using `git checkout`. Otherwise, `master` branch will be built.
+
+
+#### 2. Building dependencies
+
+QIDISlicer uses CMake and the build is quite simple, the only tricky part is resolution of dependencies. The supported and recommended way is to build the dependencies first and link to them statically. QIDISlicer source base contains a CMake script that automatically downloads and builds the required dependencies. All that is needed is to run the following (from the top of the cloned repository):
+
+    cd deps
+    mkdir build
+    cd build
+    cmake .. -DDEP_WX_GTK3=ON
+    make
+    cd ../..
+
+
+**Warning**: Once the dependency bundle is installed in a destdir, the destdir cannot be moved elsewhere. This is because wxWidgets hardcode the installation path.
+
+
+#### 3. Building QIDISlicer
+
+Now when the dependencies are compiled, all that is needed is to tell CMake that we are interested in static build and point it to the dependencies. From the top of the repository, run
+
+    mkdir build
+    cd build
+    cmake .. -DSLIC3R_STATIC=1 -DSLIC3R_GTK=3 -DSLIC3R_PCH=OFF -DCMAKE_PREFIX_PATH=$(pwd)/../deps/build/destdir/usr/local
+    make -j4
+
+And that's it. It is now possible to run the freshly built QIDISlicer binary:
+
+    cd src
+    ./qidi-slicer
+
+
+
+
+## Useful CMake flags when building dependencies
+
+- `-DDESTDIR=<target destdir>` allows to specify a directory where the dependencies will be installed. When not provided, the script creates and uses `destdir` directory where cmake is run.
+
+- `-DDEP_DOWNLOAD_DIR=<download cache dir>` specifies a directory to cache the downloaded source packages for each library. Can be useful for repeated builds, to avoid unnecessary network traffic.
+
+- `-DDEP_WX_GTK3=ON` builds wxWidgets (one of the dependencies) against GTK3 (defaults to OFF)
+
+
+## Useful CMake flags when building QIDISlicer
+- `-DSLIC3R_ASAN=ON` enables gcc/clang address sanitizer (defaults to `OFF`, requires gcc>4.8 or clang>3.1)
+- `-DSLIC3R_GTK=3` to use GTK3 (defaults to `2`). Note that wxWidgets must be built against the same GTK version.
+- `-DSLIC3R_STATIC=ON` for static build (defaults to `OFF`)
+- `-DSLIC3R_WX_STABLE=ON` to look for wxWidgets 3.0 (defaults to `OFF`)
+- `-DCMAKE_BUILD_TYPE=Debug` to build in debug mode (defaults to `Release`)
+- `-DSLIC3R_GUI=no` to build the console variant of QIDISlicer
+
+See the CMake files to get the complete list.
+
+
+
+## Building dynamically
+
+As already mentioned above, dynamic linking of dependencies is possible, but QIDISlicer team is unable to troubleshoot (Linux world is way too complex). Feel free to do so, but you are on your own. Several remarks though:
+
+The list of dependencies can be easily obtained by inspecting the CMake scripts in the `deps/` directory. Some of the dependencies don't have to be as recent as the versions listed - generally versions available on conservative Linux distros such as Debian stable, Ubuntu LTS releases or Fedora are likely sufficient. If you decide to build this way, it is your responsibility to make sure that CMake finds all required dependencies. It is possible to look at your distribution QIDISlicer package to see how the package maintainers solved the dependency issues.
+
+#### wxWidgets
+By default, QIDISlicer looks for wxWidgets 3.1. Our build script in fact downloads specific patched version of wxWidgets. If you want to link against wxWidgets 3.0 (which are still provided by most distributions because wxWidgets 3.1 have not yet been declared stable), you must set `-DSLIC3R_WX_STABLE=ON` when running CMake. Note that while QIDISlicer can be linked against wWidgets 3.0, the combination is not well tested and there might be bugs in the resulting application. 
+
+When building on ubuntu 20.04 focal fossa, the package libwxgtk3.0-gtk3-dev needs to be installed instead of libwxgtk3.0-dev and you should use:
+```
+-DSLIC3R_WX_STABLE=1 -DSLIC3R_GTK=3
+``` 
+
+## Miscellaneous
+
+### Installation
+
+At runtime, QIDISlicer needs a way to access its resource files. By default, it looks for a `resources` directory relative to its binary.
+
+If you instead want QIDISlicer installed in a structure according to the File System Hierarchy Standard, use the `SLIC3R_FHS` flag
+
+    cmake .. -DSLIC3R_FHS=1
+
+This will make QIDISlicer look for a fixed-location `share/slic3r-qidi3d` directory instead (note that the location becomes hardcoded).
+
+You can then use the `make install` target to install QIDISlicer.
+
+### Desktop Integration (QIDISlicer 2.4 and newer)
+
+If QIDISlicer is to be distributed as an AppImage or a binary blob (.tar.gz and similar), then a desktop integration support is compiled in by default: QIDISlicer will offer to integrate with desktop by manually copying the desktop file and application icon into user's desktop configuration. The built-in desktop integration is also handy on Crosstini (Linux on Chrome OS).
+
+If QIDISlicer is compiled with `SLIC3R_FHS` enabled, then a desktop integration support will not be integrated. One may want to disable desktop integration by running
+    
+    cmake .. -DSLIC3R_DESKTOP_INTEGRATION=0
+    
+when building QIDISlicer for flatpack or snap, where the desktop integration is performed by the installer.

+# Building QIDISlicer on Mac OS
+
+To build QIDISlicer on Mac OS, you will need the following software:
+
+- XCode
+- CMake
+- git
+- gettext
+
+XCode is available through Apple's App Store, the other three tools are available on
+[brew](https://brew.sh/) (use `brew install cmake git gettext` to install them).
+
+### Dependencies
+
+QIDISlicer comes with a set of CMake scripts to build its dependencies, it lives in the `deps` directory.
+Open a terminal window and navigate to QIDISlicer sources directory and then to `deps`.
+Use the following commands to build the dependencies:
+
+    mkdir build
+    cd build
+    cmake ..
+    make
+
+This will create a dependencies bundle inside the `build/destdir` directory.
+You can also customize the bundle output path using the `-DDESTDIR=<some path>` option passed to `cmake`.
+
+**Warning**: Once the dependency bundle is installed in a destdir, the destdir cannot be moved elsewhere.
+(This is because wxWidgets hardcodes the installation path.)
+
+FIXME The Cereal serialization library needs a tiny patch on some old OSX clang installations
+https://github.com/USCiLab/cereal/issues/339#issuecomment-246166717
+
+
+### Building QIDISlicer
+
+If dependencies are built without errors, you can proceed to build QIDISlicer itself.
+Go back to top level QIDISlicer sources directory and use these commands:
+
+    mkdir build
+    cd build
+    cmake .. -DCMAKE_PREFIX_PATH="$PWD/../deps/build/destdir/usr/local"
+
+The `CMAKE_PREFIX_PATH` is the path to the dependencies bundle but with `/usr/local` appended - if you set a custom path
+using the `DESTDIR` option, you will need to change this accordingly. **Warning:** the `CMAKE_PREFIX_PATH` needs to be an absolute path.
+
+The CMake command above prepares QIDISlicer for building from the command line.
+To start the build, use
+
+    make -jN
+
+where `N` is the number of CPU cores, so, for example `make -j4` for a 4-core machine.
+
+Alternatively, if you would like to use XCode GUI, modify the `cmake` command to include the `-GXcode` option:
+
+    cmake .. -GXcode -DCMAKE_PREFIX_PATH="$PWD/../deps/build/destdir/usr/local"
+
+and then open the `QIDISlicer.xcodeproj` file.
+This should open up XCode where you can perform build using the GUI or perform other tasks.
+
+### Note on Mac OS X SDKs
+
+By default QIDISlicer builds against whichever SDK is the default on the current system.
+
+This can be customized. The `CMAKE_OSX_SYSROOT` option sets the path to the SDK directory location
+and the `CMAKE_OSX_DEPLOYMENT_TARGET` option sets the target OS X system version (eg. `10.14` or similar).
+Note you can set just one value and the other will be guessed automatically.
+In case you set both, the two settings need to agree with each other. (Building with a lower deployment target
+is currently unsupported because some of the dependencies don't support this, most notably wxWidgets.)
+
+Please note that the `CMAKE_OSX_DEPLOYMENT_TARGET` and `CMAKE_OSX_SYSROOT` options need to be set the same
+on both the dependencies bundle as well as QIDISlicer itself.
+
+Official macOS QIDISlicer builds are currently (as of QIDISlicer 2.5) built against SDK 10.12 to ensure compatibility with older Macs.
+
+_Warning:_ XCode may be set such that it rejects SDKs bellow some version (silently, more or less).
+This is set in the property list file
+
+    /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Info.plist
+
+To remove the limitation, simply delete the key `MinimumSDKVersion` from that file.
+
+

+# Step by Step Visual Studio 2019 Instructions
+
+### Install the tools
+
+Install Visual Studio Community 2019 from [visualstudio.microsoft.com/vs/](https://visualstudio.microsoft.com/vs/). Older versions are not supported as QIDISlicer requires support for C++17.
+Select all workload options for C++ and make sure to launch Visual Studio after install (to ensure that the full setup completes).
+
+Install git for Windows from [gitforwindows.org](https://gitforwindows.org/)
+Download and run the exe accepting all defaults
+
+### Download sources
+
+Clone the respository.  To place it in C:\src\QIDISlicer, run:
+```
+c:> mkdir src
+c:> cd src
+c:\src> git clone https://github.com/qidi3d/QIDISlicer.git
+```
+
+### Run the automatic build script
+
+The script `build_win.bat` will automatically find the default Visual Studio installation, set up the build environment, and then run both CMake and MSBuild to generate the dependencies and application as needed. If you'd rather do these steps manually, you can skip to the [Manual Build Instructions](#manual-build-instructions) in the next section. Otherwise, just run the following command to get everything going with the default configs:
+
+```
+c:\src>cd c:\src\QIDISlicer
+c:\src\QIDISlicer>build_win.bat -d=..\QIDISlicer-deps -r=console
+```
+
+The build script will run for a while (over an hour, depending on your machine) and automatically perform the following steps:
+1. Configure and build [deps](#compile-the-dependencies) as RelWithDebInfo with `c:\src\QIDISlicer-deps` as the destination directory
+2. Configure and build all [application targets](#compile-qidislicer) as RelWithDebInfo
+3. Launch the resulting `qidi-slicer-console.exe` binary
+
+You can change the above command line options to do things like:
+* Change the destination for the dependencies by pointing `-d` to a different directory such as: `build_win.bat -d=s:\QIDISlicerDeps`
+* Open the solution in Visual Studio after the build completes by changing the `-r` switch to `-r=ide`
+* Generate a release build without debug info by adding `-c=Release` or a full debug build with `-c=Debug`
+* Perform an incremental application build (the default) with: `build_win.bat -s=app-dirty`
+* Clean and rebuild the application: `build_win.bat -s=app`
+* Clean and rebuild the dependencies: `build_win.bat -s=deps`
+* Clean and rebuild everything (app and deps): `build_win.bat -s=all`
+* _The full list of build script options can be listed by running:_ `build_win.bat -?`
+
+### Troubleshooting
+
+You're best off initiating builds from within Visual Studio for day-to-day development. However, the `build_win.bat` script can be very helpful if you run into build failures after updating your source tree. Here are some tips to keep in mind:
+* The last several lines of output from `build_win.bat` will usually have the most helpful error messages.
+* If CMake complains about missing binaries or paths (e.g. after updating Visual Studio), building with `build_win.bat` will force CMake to regenerate its cache on an error.
+* After a deps change, you may just need to rebuild everything with the `-s=all` switch.
+* Reading through the instructions in the next section may help diagnose more complex issues.
+
+# Manual Build Instructions
+
+_Follow the steps below if you want to understand how to perform a manual build, or if you're troubleshooting issues with the automatic build script._
+
+### Compile the dependencies.
+Dependencies are updated seldomly, thus they are compiled out of the QIDISlicer source tree.
+Go to the Windows Start Menu and Click on "Visual Studio 2019" folder, then select the ->"x64 Native Tools Command Prompt" to open a command window and run the following:
+```
+cd c:\src\QIDISlicer\deps
+mkdir build
+cd build
+cmake .. -G "Visual Studio 16 2019" -DDESTDIR="c:\src\QIDISlicer-deps"
+
+msbuild /m ALL_BUILD.vcxproj // This took 13.5 minutes on my machine: core I7-7700K @ 4.2Ghz with 32GB main memory and 20min on a average laptop
+```
+
+### Generate Visual Studio project file for QIDISlicer, referencing the precompiled dependencies.
+Go to the Windows Start Menu and Click on "Visual Studio 2019" folder, then select the ->"x64 Native Tools Command Prompt" to open a command window and run the following:
+```
+cd c:\src\QIDISlicer\
+mkdir build
+cd build
+cmake .. -G "Visual Studio 16 2019" -DCMAKE_PREFIX_PATH="c:\src\QIDISlicer-deps\usr\local"
+```
+
+Note that `CMAKE_PREFIX_PATH` must be absolute path. A relative path like "..\..\QIDISlicer-deps\usr\local" does not work.
+
+### Compile QIDISlicer. 
+
+Double-click c:\src\QIDISlicer\build\QIDISlicer.sln to open in Visual Studio 2019.
+OR
+Open Visual Studio for C++ development (VS asks this the first time you start it).
+
+Select QIDISlicer_app_gui as your startup project (right-click->Set as Startup Project).
+
+Run Build->Rebuild Solution once to populate all required dependency modules.  This is NOT done automatically when you build/run.  If you run both Debug and Release variants, you will need to do this once for each.
+
+Debug->Start Debugging or press F5
+
+QIDISlicer should start. You're up and running!
+
+note: Thanks to @douggorgen for the original guide, as an answer for a issue 
+
+
+# The below information is out of date, but still useful for reference purposes
+
+We have switched to MS Visual Studio 2019.
+
+We don't use MSVS 2013 any more. At the moment we are in the process of creating new pre-built dependency bundles
+and updating this document. In the meantime, you will need to compile the dependencies yourself
+[the same way as before](#building-the-dependencies-package-yourself)
+except with CMake generators for MSVS 2019 instead of 2013.
+
+Thank you for understanding.
+
+---
+
+# Building QIDISlicer on Microsoft Windows
+
+~~The currently supported way of building QIDISlicer on Windows is with CMake and MS Visual Studio 2013.
+You can use the free [Visual Studio 2013 Community Edition](https://www.visualstudio.com/vs/older-downloads/).
+CMake installer can be downloaded from [the official website](https://cmake.org/download/).~~
+
+~~Building with newer versions of MSVS (2015, 2017) may work too as reported by some of our users.~~
+
+_Note:_ Thanks to [**@supermerill**](https://github.com/supermerill) for testing and inspiration for this guide.
+
+### Dependencies
+
+On Windows QIDISlicer is built against statically built libraries.
+~~We provide a prebuilt package of all the needed dependencies. This package only works on Visual Studio 2013, so~~ if you are using a newer version of Visual Studio, you need to compile the dependencies yourself as per [below](#building-the-dependencies-package-yourself).
+The package comes in a several variants:
+
+  - ~~64 bit, Release mode only (41 MB, 578 MB unpacked)~~
+  - ~~64 bit, Release and Debug mode (88 MB, 1.3 GB unpacked)~~
+  - ~~32 bit, Release mode only (38 MB, 520 MB unpacked)~~
+  - ~~32 bit, Release and Debug mode (74 MB, 1.1 GB unpacked)~~
+
+When unsure, use the _Release mode only_ variant, the _Release and Debug_ variant is only needed for debugging & development.
+
+If you're unsure where to unpack the package, unpack it into `C:\local\` (but it can really be anywhere).
+
+Alternatively you can also compile the dependencies yourself, see below.
+
+### Building QIDISlicer with Visual Studio
+
+First obtain the QIDISlicer sources via either git or by extracting the source archive.
+
+Then you will need to note down the so-called 'prefix path' to the dependencies, this is the location of the dependencies packages + `\usr\local` appended.
+For example on 64 bits this would be `C:\local\destdir-64\usr\local`. The prefix path will need to be passed to CMake.
+
+When ready, open the relevant Visual Studio command line and `cd` into the directory with QIDISlicer sources.
+Use these commands to prepare Visual Studio solution file:
+
+    mkdir build
+    cd build
+    cmake .. -G "Visual Studio 12 Win64" -DCMAKE_PREFIX_PATH="<insert prefix path here>"
+
+Note that if you're building a 32-bit variant, you will need to change the `"Visual Studio 12 Win64"` to just `"Visual Studio 12"`.
+
+Conversely, if you're using Visual Studio version other than 2013, the version number will need to be changed accordingly.
+
+If `cmake` has finished without errors, go to the build directory and open the `QIDISlicer.sln` solution file in Visual Studio.
+Before building, make sure you're building the right project (use one of those starting with `QIDISlicer_app_...`) and that you're building
+with the right configuration, i.e. _Release_ vs. _Debug_. When unsure, choose _Release_.
+Note that you won't be able to build a _Debug_ variant against a _Release_-only dependencies package.
+
+#### Installing using the `INSTALL` project
+
+QIDISlicer can be run from the Visual Studio or from Visual Studio's build directory (`src\Release` or `src\Debug`),
+but for longer-term usage you might want to install somewhere using the `INSTALL` project.
+By default, this installs into `C:\Program Files\QIDISlicer`.
+To customize the install path, use the `-DCMAKE_INSTALL_PREFIX=<path of your choice>` when invoking `cmake`.
+
+### Building from the command line
+
+There are several options for building from the command line:
+
+- [msbuild](https://docs.microsoft.com/en-us/visualstudio/msbuild/msbuild-reference?view=vs-2017&viewFallbackFrom=vs-2013)
+- [Ninja](https://ninja-build.org/)
+- [nmake](https://docs.microsoft.com/en-us/cpp/build/nmake-reference?view=vs-2017)
+
+To build with msbuild, use the same CMake command as in previous paragraph and then build using
+
+    msbuild /m /P:Configuration=Release ALL_BUILD.vcxproj
+
+To build with Ninja or nmake, replace the `-G` option in the CMake call with `-G Ninja` or `-G "NMake Makefiles"` , respectively.
+Then use either `ninja` or `nmake` to start the build.
+
+To install, use `msbuild /P:Configuration=Release INSTALL.vcxproj` , `ninja install` , or `nmake install` .
+
+### Building the dependencies package yourself
+
+The dependencies package is built using CMake scripts inside the `deps` subdirectory of QIDISlicer sources.
+(This is intentionally not interconnected with the CMake scripts in the rest of the sources.)
+
+Open the preferred Visual Studio command line (64 or 32 bit variant) and `cd` into the directory with QIDISlicer sources.
+Then `cd` into the `deps` directory and use these commands to build:
+
+    mkdir build
+    cd build
+    cmake .. -G "Visual Studio 16 2019" -DDESTDIR="C:\local\destdir-custom"
+    msbuild /m ALL_BUILD.vcxproj
+
+You can also use the Visual Studio GUI or other generators as mentioned above.
+
+The `DESTDIR` option is the location where the bundle will be installed.
+This may be customized. If you leave it empty, the `DESTDIR` will be placed inside the same `build` directory.
+
+Warning: If the `build` directory is nested too deep inside other folders, various file paths during the build
+become too long and the build might fail due to file writing errors (\*). For this reason, it is recommended to
+place the `build` directory relatively close to the drive root.
+
+Note that the build variant that you may choose using Visual Studio (i.e. _Release_ or _Debug_ etc.) when building the dependency package is **not relevant**.
+The dependency build will by default build _both_ the _Release_ and _Debug_ variants regardless of what you choose in Visual Studio.
+You can disable building of the debug variant by passing the
+
+    -DDEP_DEBUG=OFF
+
+option to CMake, this will only produce a _Release_ build.
+
+Refer to the CMake scripts inside the `deps` directory to see which dependencies are built in what versions and how this is done.
+
+\*) Specifically, the problem arises when building boost. Boost build tool appends all build options into paths of
+intermediate files, which are not handled correctly by either `b2.exe` or possibly `ninja` (?).

+# Localization and translation guide
+
+The purpose of this guide is to describe how to contribute to the QIDISlicer translations. We use GNUgettext for extracting string resources from the project and PoEdit for editing translations.
+
+Those can be downloaded here: 
+-    https://sourceforge.net/directory/os:windows/?q=gnu+gettext GNUgettext package contains a set of tools to extract strings from the source code and to create the translation Catalog.
+-    https://poedit.net PoEdit provides good interface for the translators.
+
+After GNUgettext is installed, it is recommended to add the path to gettext/bin to PATH variable.
+
+Full manual for GNUgettext can be seen here: http://www.gnu.org/software/gettext/manual/gettext.html
+
+
+### Scenario 1. How do I add a translation or fix an existing translation
+1. Get PO-file from corresponding folder here:
+https://github.com/qidi3d/QIDISlicer/tree/master/resources/localization
+2. Open this file in PoEdit as "Edit a translation"
+3. Apply your corrections to the translation
+4. Push changed QIDISlicer.po and QIDISlicer.mo (will create automatically after saving of QIDISlicer.po in PoEdit) into the original folder.
+
+### Scenario 2. How do I add a new language support
+1. Get file QIDISlicer.pot here :
+https://github.com/qidi3d/QIDISlicer/tree/master/resources/localization
+2. Open it in PoEdit for "Create new translation"
+3. Select Translation Language (for example French).
+4. As a result you will have fr.po - the file containing translation to French.
+Notice. When the translation is complete you need to:
+    - Rename the file to QIDISlicer.po
+    - Click "Save file" button. QIDISlicer.mo will be created immediately
+    - Both QIDISlicer.po and QIDISlicer.mo have to be saved here:
+https://github.com/qidi3d/QIDISlicer/tree/master/resources/localization/fr
+( name of folder "fr" means "French" - the translation language). 
+
+### Scenario 3. How do I add a new text resource when implementing a feature to QIDISlicer
+Each string resource in QIDISlicer available for translation needs to be explicitly marked using L() macro like this:
+```C++
+auto msg = L("This message to be localized")
+```
+To get translated text use one of needed macro/function (`_(s)` or `_CHB(s)` ).
+If you add new file resource, add it to the list of files containing macro `L()`
+
+### Scenario 4. How do I use GNUgettext to localize my own application taking QIDISlicer as an example
+
+1.  For convenience create a list of files with this macro `L(s)`. We have 
+https://github.com/qidi3d/QIDISlicer/tree/master/resources/localization/list.txt.
+
+2.  Create template file(*.POT) with GNUgettext command:
+    ```
+        xgettext --keyword=L --add-comments=TRN --from-code=UTF-8 --debug -o QIDISlicer.pot -f list.txt
+    ```
+
+    Use flag `--from-code=UTF-8` to specify that the source strings are in UTF-8 encoding
+    Use flag `--debug` to correctly extract formatted strings(used %d, %s etc.)
+
+3.  Create PO- and MO-files for your project as described above.
+
+4.  To merge old PO-file with strings from created new POT-file use command:
+    ```
+        msgmerge -N -o new.po old.po new.pot
+    ```
+    Use option `-N` to not using fuzzy matching when an exact match is not found.
+
+5.  To concatenate old PO-file with strings from new PO-file use command:
+    ```
+        msgcat -o new.po old.po
+    ```
+
+6.  Create an English translation catalog with command:
+    ```    
+        msgen -o new.po old.po
+    ```
+    Notice, in this Catalog it will be totally same strings for initial text and translated.
+
+When you have Catalog to translation open POT or PO file in PoEdit and start translating.
+
+
+## General guidelines for QIDISlicer translators
+
+
+- We recommend using *PoEdit* application for translation (as described above). It will help you eliminate most punctuation errors and will show you strings with "random" translations (if the fuzzy parameter was used).
+
+- To check how the translated text looks on the UI elements, test it :) If you use *PoEdit*, all you need to do is save the file. At this point, a MO file will be created. Rename it QIDISlicer.mo, and you can run QIDISlicer (see above).
+
+- If you see an encoding error (garbage characters instead of Unicode) somewhere in QIDISlicer, report it. It is likely not a problem of your translation, but a bug in the software.
+
+- See on which UI elements the translated phrase will be used. Especially if it's a button, it is very important to decide on the translation and not write alternative translations in parentheses, as this will significantly increase the width of the button, which is sometimes highly undesirable:
+
+![Long text on button](images/long_text_on_button.png)
+
+- If you decide to use autocorrect or any batch processing tool, the output requires very careful proofreading. It is very easy to make it do changes that break things big time.
+
+- **Any formatting parts of the phrases must remain unchanged.** For example, you should not change `%1%` to `%1 %`, you should not change `%%` to `%` (for percent sign) and similar. This will lead to application crashes.
+
+- Please pay attention to spaces, line breaks (\n) and punctuation marks. **Don't add extra line breaks.** This is especially important for parameter names.
+
+- Description of the parameters should not contain units of measurement. For example, "Enable fan if layer print time is less than ~~n seconds~~"
+
+- For units of measurement, use the international system of units. Use "s" instead of "sec".
+
+- If the phrase doesn't have a dot at the end, don't add it. And if it does, then don't forget to :)
+
+- It is useful to stick to the same terminology in the application (especially with basic terms such as "filament" and similar). Stay consistent. Otherwise it will confuse users.

+# Slic3r PE 1.40 configuration update
+
+Slic3r PE 1.40.0 comes with a major re-work of the way configuration presets work.
+There are three new features:
+
++ A two-tier system of presets being divided into _System_ and _User_ groups
++ Configuration snapshots
++ Configuration updating from the internet
+
+## System and User presets
+
+- _System preset_: These are the presets that come with Slic3r PE installation. They come from a vendor configuration bundle (not individual files like before). They are **read-only** – a user cannot modify them, but may instead create a derived User preset based on a System preset
+- _User preset_: These are regular presets stored in files just like before. Additionally, they may be derived (inherited) from one of the System presets
+
+A derived User preset keeps track of which settings are inherited from the parent System preset and which are modified by the user. When a system preset is updated (either via installation of a new Slic3r or automatically from the internet), in a User preset the settings that are modified by the user will stay that way, while the ones that are inherited reflect the updated System preset.
+
+This system ensures that we don't overwrite user's settings when there is an update to the built in presets.
+
+Slic3r GUI now displays accurately which settings are inherited and which are modified.
+A setting derived from a System preset is represented by green label and a locked lock icon:
+
+![a system setting](setting_sys.png)
+
+A settings modified in a User preset has an open lock icon:
+
+![a user setting](setting_user.png)
+
+Clicking the open lock icon restores the system setting.
+
+Additionally, any setting that is modified but not yet saved onto disk is represented by orange label and a back-arrow:
+
+![a modified setting](setting_mod.png)
+
+Clicking the back-arrow restores the value that was previously saved in this Preset.
+
+## Configuration snapshots
+
+Configuration snapshots can now be taken via the _Configuration_ menu.
+A snapshot contains complete configuration from the point when the snapshot was taken.
+Users may move back and forth between snapshots at will using a dialog:
+
+![snapshots dialog](snapshots_dialog.png)
+
+
+# Updating from the internet
+
+Slic3r PE 1.40.0 checks for updates of the built-in System presets and downloads them.
+The first-time configuration assistant will ask you if you want to enable this feature - it is **not** mandatory.
+
+Updates are checked for and downloaded in the background. If there's is an update, Slic3r will prompt about it 
+next time it is launched, never during normal program operation. An update may be either accepted or refused.
+Before any update is applied a configuration snapshot (as described above) is taken.
