  32  # Configuration subroutine to validate and canonicalize a configuration type.
  33  # Supply the specified configuration type as an argument.
  34  # If it is invalid, we print an error message on stderr and exit with code 1.
  35  # Otherwise, we print the canonical config type on stdout and succeed.
  36

  40  # This file is supposed to be the same for all GNU packages
  41  # and recognize all the CPU types, system types and aliases
  42  # that are meaningful with *any* GNU software.
  43  # Each package is responsible for reporting which valid configurations
  44  # it does not support.  The user should be able to distinguish
  45  # a failure to support a valid configuration from a meaningless
  46  # configuration.
  47  
  48  # The goal of this file is to map all the various variations of a given
  49  # machine specification into a single specification in the form:
  50  #	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
  51  # or in some cases, the newer four-part form:
  52  #	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
  53  # It is wrong to echo any other type of specification.
  54  
  55  # The "shellcheck disable" line above the timestamp inhibits complaints
  56  # about features and limitations of the classic Bourne shell that were
  57  # superseded or lifted in POSIX.  However, this script identifies a wide
  58  # variety of pre-POSIX systems that do not have POSIX shells at all, and
  59  # even some reasonably current systems (Solaris 10 as case-in-point) still
  60  # have a pre-POSIX /bin/sh.
