+"""fuse_gmock_files.py v0.1.0
+Fuses Google Mock and Google Test source code into two .h files and a .cc file.
+
+SYNOPSIS
+ fuse_gmock_files.py [GMOCK_ROOT_DIR] OUTPUT_DIR
+
+ Scans GMOCK_ROOT_DIR for Google Mock and Google Test source
+ code, assuming Google Test is in the GMOCK_ROOT_DIR/gtest
+ sub-directory, and generates three files:
+ OUTPUT_DIR/gtest/gtest.h, OUTPUT_DIR/gmock/gmock.h, and
+ OUTPUT_DIR/gmock-gtest-all.cc. Then you can build your tests
+ by adding OUTPUT_DIR to the include search path and linking
+ with OUTPUT_DIR/gmock-gtest-all.cc. These three files contain
+ everything you need to use Google Mock. Hence you can
+ "install" Google Mock by copying them to wherever you want.
+
+ GMOCK_ROOT_DIR can be omitted and defaults to the parent
+ directory of the directory holding this script.
+
+EXAMPLES
+ ./fuse_gmock_files.py fused_gmock
+ ./fuse_gmock_files.py path/to/unpacked/gmock fused_gmock
+
+This tool is experimental. In particular, it assumes that there is no
+conditional inclusion of Google Mock or Google Test headers. Please
+report any problems to googlemock@googlegroups.com. You can read
+http://code.google.com/p/googlemock/wiki/CookBook for more
+information.
