		53	# @ECLASS-VARIABLE: RUBY_S
		54	# @DEFAULT_UNSET
		55	# @DESCRIPTION:
		56	# If defined this variable determines the source directory name after
		57	# unpacking. This defaults to the name of the package. Note that this
		58	# variable supports a wildcard mechanism to help with github tarballs
		59	# that contain the commit hash as part of the directory name.
		60
		61	# @ECLASS-VARIABLE: RUBY_QA_ALLOWED_LIBS
		62	# @DEFAULT_UNSET
		63	# @DESCRIPTION:
		64	# If defined this variable contains a whitelist of shared objects that
		65	# are allowed to exist even if they don't link to libruby. This avoids
		66	# the QA check that makes this mandatory. This is most likely not what
		67	# you are looking for if you get the related "Missing links" QA warning,
		68	# since the proper fix is almost always to make sure the shared object
		69	# is linked against libruby. There are cases were this is not the case
		70	# and the shared object is generic code to be used in some other way
		71	# (e.g. selenium's firefox driver extension). When set this argument is
		72	# passed to "grep -E" to remove reporting of these shared objects.
