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

33# This file is supposed to be the same for all GNU packages
34# and recognize all the CPU types, system types and aliases
35# that are meaningful with *any* GNU software.
36# Each package is responsible for reporting which valid configurations
37# it does not support.  The user should be able to distinguish
38# a failure to support a valid configuration from a meaningless
39# configuration.

41# The goal of this file is to map all the various variations of a given
42# machine specification into a single specification in the form:
43#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
44# or in some cases, the newer four-part form:
45#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
46# It is wrong to echo any other type of specification.
