  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:

  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.
