#
# Provide support for ghostscript ports.
#
# Feature:	ghostscript
# Usage:	USES=ghostscript or USES=ghostscript:args
# Valid ARGS:	<version>, build, run, nox11, agpl
#
# version 	The chooseable versions are 7, 8 and 9. If no version is
#		specified version 9 is selected.
#
#		USES=ghostscript:7	# Use Ghostscript 7
#		USES=ghostscript:run	# Use the set default Ghostscript as a run dependancy
#		USES=ghostscript:8,build # Use ghostscript 8 as a build dependancy.
#
# nox11		Indicate that the Ghostscript nox11 port is required.
# agpl		Indicate that the Ghostscript apgl port is required.
# build		Indicates that Ghostscript is needed at build time and adds
#		it as BUILD_DEPENDS.
# run		Indicates that Ghostscript is needed at run time and adds
#		it as RUN_DEPENDS.
#
# If build and run are omitted, Ghostscript will be added as BUILD_DEPENDS and
# RUN_DEPENDS.
