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.
41
42# You can get the latest version of this script from:
43# http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD
44
45# This file is supposed to be the same for all GNU packages
46# and recognize all the CPU types, system types and aliases
47# that are meaningful with *any* GNU software.
48# Each package is responsible for reporting which valid configurations
49# it does not support.  The user should be able to distinguish
50# a failure to support a valid configuration from a meaningless
51# configuration.
52
53# The goal of this file is to map all the various variations of a given
54# machine specification into a single specification in the form:
55#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
56# or in some cases, the newer four-part form:
57#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
58# It is wrong to echo any other type of specification.
