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.
39
40# This file is supposed to be the same for all GNU packages
41# and recognize all the CPU types, system types and aliases
42# that are meaningful with *any* GNU software.
43# Each package is responsible for reporting which valid configurations
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.
47
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.
