30	# Configuration subroutine to validate and canonicalize a configuration type.

33	# Otherwise, we print the canonical config type on stdout and succeed.

42	# it does not support. The user should be able to distinguish
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
51	# It is wrong to echo any other type of specification.
