# @BLURB: This eclass provides support for autotools based mysql releases
# @DESCRIPTION:
# The mysql-autotools.eclass provides the support to build the mysql
# ebuilds using the autotools build system. This eclass provides
# the src_unpack, src_prepare, src_configure, src_compile, scr_install,
# pkg_preinst, pkg_postinst, pkg_config and pkg_postrm phase hooks.
