     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.

     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     57# superseded or lifted in POSIX.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.
