DESCRIPTION="Cross-platform 3D realtime strategy game"
HOMEPAGE="http://www.megaglest.org/"

SRC_URI="mirror://sourceforge/${PN}/${PN}-source-${PV}.tar.xz"

KEYWORDS="~amd64 ~x86"
IUSE="debug libircclient miniupnpc static-libs"

# MegaGlest configuration script will only attempt to locate an external libircclient or miniupnpc if -DWANT_STATIC_LIBS="off"
# If static-libs is off and an external copy is not present, it will use an embedded libircclient or miniupnpc.
# It will ALWAYS use embedded versions of these libraries if static-libs is enabled.
