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.
38
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.
