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

43	# a failure to support a valid configuration from a meaningless
44	# configuration.

49	# or in some cases, the newer four-part form:
50	# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
