%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 5 to 10 times speedup in common compilations.

To enable ccache's default use, the system admin should modify 
%{_sysconfdir}/sysconfig/ccache to "yes". If its default use is not 
enabled and you wish to use it, simply add %{_prefix}/%{_lib}/ccache/bin/ to 
the start of your \$PATH
