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

37
38# This file is supposed to be the same for all GNU packages
39# and recognize all the CPU types, system types and aliases
40# that are meaningful with *any* GNU software.
41# Each package is responsible for reporting which valid configurations
42# it does not support.  The user should be able to distinguish
43# a failure to support a valid configuration from a meaningless
44# configuration.
45
46# The goal of this file is to map all the various variations of a given
47# machine specification into a single specification in the form:
48#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
49# or in some cases, the newer four-part form:
50#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
51# It is wrong to echo any other type of specification.
