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.

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

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

51	# machine specification into a single specification in the form:
52	# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
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.
