Usage:
    ccache [options]
    ccache compiler [compiler options]
    compiler [compiler options]          (via symbolic link)

Options:
    -c, --cleanup         delete old files and recalculate size counters
                          (normally not needed as this is done automatically)
    -C, --clear           clear the cache completely (except configuration)
    -F, --max-files=N     set maximum number of files in cache to N (use 0 for

    -M, --max-size=SIZE   set maximum size of cache to SIZE (use 0 for no
                          limit); available suffixes: k, M, G, T (decimal) and
                          Ki, Mi, Gi, Ti (binary); default suffix: G
    -o, --set-config=K=V  set configuration key K to value V
    -p, --print-config    print current configuration options
    -s, --show-stats      show statistics summary
    -z, --zero-stats      zero statistics counters
