-"""fuse_gtest_files.py v0.2.0
-Fuses Google Test source code into a .h file and a .cc file.
-
-SYNOPSIS
-       fuse_gtest_files.py [GTEST_ROOT_DIR] OUTPUT_DIR
-
-       Scans GTEST_ROOT_DIR for Google Test source code, and generates
-       two files: OUTPUT_DIR/gtest/gtest.h and OUTPUT_DIR/gtest/gtest-all.cc.
-       Then you can build your tests by adding OUTPUT_DIR to the include
-       search path and linking with OUTPUT_DIR/gtest/gtest-all.cc.  These
-       two files contain everything you need to use Google Test.  Hence
-       you can "install" Google Test by copying them to wherever you want.
-
-       GTEST_ROOT_DIR can be omitted and defaults to the parent
-       directory of the directory holding this script.
-
-EXAMPLES
-       ./fuse_gtest_files.py fused_gtest
-       ./fuse_gtest_files.py path/to/unpacked/gtest fused_gtest
-
-This tool is experimental.  In particular, it assumes that there is no

-The `gtest-config' script provides access to the necessary compile and linking
-flags to connect with Google C++ Testing Framework, both in a build prior to
-installation, and on the system proper after installation. The installation
-overrides may be issued in combination with any other queries, but will only
-affect installation queries if called on a built but not installed gtest. The
-installation queries may not be issued with any other types of queries, and
-only one installation query may be made at a time. The version queries and
-compiler flag queries may be combined as desired but not mixed. Different
-version queries are always combined with logical "and" semantics, and only the
-last of any particular query is used while all previous ones ignored. All
-versions must be specified as a sequence of numbers separated by periods.
-Compiler flag queries output the union of the sets of flags when combined.
-
- Examples:
-  gtest-config --min-version=1.0 || echo "Insufficient Google Test version."
-
-  g++ $(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp
-  g++ $(gtest-config --ldflags --libs) -o foo foo.o
-
-  # When using a built but not installed Google Test:
-  g++ $(../../my_gtest_build/scripts/gtest-config ...) ...
-
-  # When using an installed Google Test, but with installation overrides:
-  export GTEST_PREFIX="/opt"
-  g++ $(gtest-config --libdir="/opt/lib64" ...) ...

-  --libdir=<dir>             overrides the library installation prefix
-  --includedir=<dir>         overrides the header file installation prefix

- Installation Queries:

-  --exec-prefix              executable installation prefix
-  --libdir                   library installation directory
-  --includedir               header file installation directory
-  --version                  the version of the Google Test installation
-
- Version Queries:
-  --min-version=VERSION      return 0 if the version is at least VERSION
-  --exact-version=VERSION    return 0 if the version is exactly VERSION
-  --max-version=VERSION      return 0 if the version is at most VERSION

- Compilation Flag Queries:

-"""Script for branching Google Test/Mock wiki pages for a new version.
-
-SYNOPSIS
-       release_docs.py NEW_RELEASE_VERSION
-
-       Google Test and Google Mock's external user documentation is in
-       interlinked wiki files.  When we release a new version of
-       Google Test or Google Mock, we need to branch the wiki files
-       such that users of a specific version of Google Test/Mock can
-       look up documentation relevant for that version.  This script
-       automates that process by:
-
-         - branching the current wiki pages (which document the
-           behavior of the SVN trunk head) to pages for the specified
-           version (e.g. branching FAQ.wiki to V2_6_FAQ.wiki when
-           NEW_RELEASE_VERSION is 2.6);
-         - updating the links in the branched files to point to the branched
-           version (e.g. a link in V2_6_FAQ.wiki that pointed to
-           Primer.wiki#Anchor will now point to V2_6_Primer.wiki#Anchor).
-
-       NOTE: NEW_RELEASE_VERSION must be a NEW version number for
-       which the wiki pages don't yet exist; otherwise you'll get SVN
-       errors like "svn: Path 'V1_7_PumpManual.wiki' is not a
-       directory" when running the script.
-
-EXAMPLE
-       $ cd PATH/TO/GTEST_SVN_WORKSPACE/trunk
-       $ scripts/release_docs.py 2.6  # create wiki pages for v2.6
-       $ svn status                   # verify the file list
-       $ svn diff                     # verify the file contents
-       $ svn commit -m "release wiki pages for v2.6"
