#		USES=ghostscript:10	    # Use Ghostscript 10
#		USES=ghostscript:run	# Use to set default Ghostscript as a run dependency
#		USES=ghostscript:10,build # Use Ghostscript 10 as a build dependency.
#
# build		Ghostscript is used as BUILD_DEPENDS
# lib		Ghostscript is used as LIB_DEPENDS
# run		Ghostscript is used as RUN_DEPENDS
# test		Ghostscript is used as TEST_DEPENDS
#
# x11		Indicate that X11 support is required.
