+To use ccache with **non-Portage** C compiling, add
+${EPREFIX}/usr/lib/ccache/bin to the beginning of your path, before ${EPREFIX}/usr/bin.
+Portage 2.0.46-r11+ will automatically take advantage of ccache with
+no additional steps.  If this is your first install of ccache, type
+something like this to set a maximum cache size of 2GB:\\n
+# ccache -M 2G\\n
+If you are upgrading from an older version than 3.x you should clear all of your caches like so:\\n
+# CCACHE_DIR='${CCACHE_DIR:-${PORTAGE_TMPDIR}/ccache}' ccache -C\\n
+ccache now supports sys-devel/clang and dev-lang/icc, too!"
