	DOC_CONTENTS="
To use ccache with **non-Portage** C compiling, add
${EPREFIX}/usr/$(get_libdir)/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!"
