  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.

  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.
