This directory contains a version of ccache. The initial version was based on ccache-2.4 plus 
debian patches 01-02, 04-14, see the debian/patches subdirectory. The ccache-win32-2.4 modifications
to ccache-2.4 have also been merged in.

Changes have been made to support caching the output from SWIG. The ability to cache c/c++ compiler 
output has been retained.

Additional features added are the CCACHE_VERBOSE and CCACHE_SWIG environment variables, see docs.
