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

39	# This file is supposed to be the same for all GNU packages
40	# and recognize all the CPU types, system types and aliases
41	# that are meaningful with any GNU software.
42	# Each package is responsible for reporting which valid configurations
43	# it does not support. The user should be able to distinguish
44	# a failure to support a valid configuration from a meaningless
45	# configuration.
46
47	# The goal of this file is to map all the various variations of a given
48	# machine specification into a single specification in the form:
49	# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
50	# or in some cases, the newer four-part form:
51	# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
52	# It is wrong to echo any other type of specification.
