%description
Ccache is a compiler cache. It acts as a caching pre-processor to C/C++
compilers, using the -E compiler switch and a hash to detect when a
compilation can be satisfied from cache. This often results in a
speedup for common compilations.

# SHARING A CACHE
# 
# A group of developers can increase the cache hit rate by
# sharing a cache directory. The hard links however cause unwanted side
# effects, as all links to a cached file share the file's modification
# timestamp. This results in false dependencies to be triggered by
# timestamp-based build systems whenever another user links to an
# existing file. Typically, users will see that their libraries and
# binaries are relinked without reason. To share a cache without side
# effects, the following conditions need to be met:   
# 
#     * Use the same CCACHE_DIR environment variable setting
#     * Set the CCACHE_NOLINK environment variable
#     * Make sure everyone sets the CCACHE_UMASK environment variable to
#       002, this ensures that cached files are accessible to everyone
#       in the group. 
#     * Make sure that all users have write permission in the entire
#       cache directory (and that you trust all users of the shared
#       cache). 
#     * Make sure that the setgid bit is set on all directories in the
#       cache. This tells the filesystem to inherit group ownership for
#       new directories. The command "chmod g+s `find $CCACHE_DIR -type
#       d`" might be useful for this.
