+# @BLURB: This eclass provides most of the functions for mysql ebuilds
+# @DESCRIPTION:
+# The mysql-multilib.eclass is the base eclass to build the mysql and
+# alternative projects (mariadb and percona) ebuilds.
+# This eclass uses the mysql-cmake eclass for the
+# specific bits related to the build system.
+# It provides the src_unpack, src_prepare, src_configure, src_compile,
+# src_install, pkg_preinst, pkg_postinst, pkg_config and pkg_postrm
+# phase hooks.
