# @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.
