		52	# @DESCRIPTION:
		53	# If defined this variable determines the source directory name after

		55	# variable supports a wildcard mechanism to help with github tarballs

		58	# @ECLASS-VARIABLE: RUBY_QA_ALLOWED_LIBS
		59	# @DEFAULT_UNSET
		60	# @DESCRIPTION:
		61	# If defined this variable contains a whitelist of shared objects that
		62	# are allowed to exist even if they don't link to libruby. This avoids
		63	# the QA check that makes this mandatory. This is most likely not what
		64	# you are looking for if you get the related "Missing links" QA warning,
		65	# since the proper fix is almost always to make sure the shared object
		66	# is linked against libruby. There are cases were this is not the case
		67	# and the shared object is generic code to be used in some other way
		68	# (e.g. selenium's firefox driver extension). When set this argument is
		69	# passed to "grep -E" to remove reporting of these shared objects.
