	35	# Configuration subroutine to validate and canonicalize a configuration type.
	36	# Supply the specified configuration type as an argument.

	48	# a failure to support a valid configuration from a meaningless
	49	# configuration.

	53	# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
	54	# or in some cases, the newer four-part form:
	55	# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
	56	# It is wrong to echo any other type of specification.
