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

	40	# This file is supposed to be the same for all GNU packages

	44	# it does not support. The user should be able to distinguish
	45	# a failure to support a valid configuration from a meaningless
	46	# configuration.

	48	# The goal of this file is to map all the various variations of a given
	49	# machine specification into a single specification in the form:
	50	# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
	51	# or in some cases, the newer four-part form:
	52	# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
	53	# It is wrong to echo any other type of specification.
