	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.

	38	# This file is supposed to be the same for all GNU packages
	39	# and recognize all the CPU types, system types and aliases
	40	# that are meaningful with any GNU software.
	41	# Each package is responsible for reporting which valid configurations
	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.
	45
	46	# The goal of this file is to map all the various variations of a given
	47	# machine specification into a single specification in the form:
	48	# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
	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.
