  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.
