You can get statistics on the cache (its size, number of hits,
misses, etc.) by running +make ccache-stats+.
+
+The make target +cache-options+ and the +CCACHE_OPTIONS+ variable
+provide more generic access to the ccache. For example
+
+-----------------
+# set cache limit size
+make CCACHE_OPTIONS="--max-size=5G" ccache-options
+
+# zero statistics counters
+make CCACHE_OPTIONS="--zero-stats" ccache-options
