# @PROVIDES: meson meson-multilib
# @BLURB: Reduces code duplication in the X11 ebuilds.
# @DESCRIPTION:
# This eclass makes trivial X ebuilds possible for apps, drivers,
# and more. Many things that would normally be done in various functions
# can be accessed by setting variables instead, such as patching,
# passing options to meson and installing docs.
#
# All you need to do in a basic ebuild is inherit this eclass and set
# DESCRIPTION, KEYWORDS and RDEPEND/DEPEND. If your package is hosted
# with the other X packages, you don't need to set SRC_URI. Pretty much
# everything else should be automatic.
