# @BLURB: This eclass provides most of the functions for mysql ebuilds
# @DESCRIPTION:
# The mysql.eclass provides almost all the code to build the mysql ebuilds
# including the src_unpack, src_prepare, src_configure, src_compile,
# scr_install, pkg_preinst, pkg_postinst, pkg_config and pkg_postrm
# phase hooks.
