	37	# Configuration subroutine to validate and canonicalize a configuration type.
	38	# Supply the specified configuration type as an argument.
	39	# If it is invalid, we print an error message on stderr and exit with code 1.
	40	# Otherwise, we print the canonical config type on stdout and succeed.

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

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