  30# Configuration subroutine to validate and canonicalize a configuration type.
  31# Supply the specified configuration type as an argument.
  32# If it is invalid, we print an error message on stderr and exit with code 1.
  33# Otherwise, we print the canonical config type on stdout and succeed.
  34
  35# You can get the latest version of this script from:
  36# http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD
  37
  38# This file is supposed to be the same for all GNU packages
  39# and recognize all the CPU types, system types and aliases
  40# that are meaningful with *any* GNU software.
  41# Each package is responsible for reporting which valid configurations
  42# it does not support.  The user should be able to distinguish
  43# a failure to support a valid configuration from a meaningless
  44# configuration.
  45
  46# The goal of this file is to map all the various variations of a given
  47# machine specification into a single specification in the form:
  48#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
  49# or in some cases, the newer four-part form:
  50#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
  51# It is wrong to echo any other type of specification.
