63# Configuration subroutine to validate and canonicalize a configuration type.
64# Supply the specified configuration type as an argument.
65# If it is invalid, we print an error message on stderr and exit with code 1.
66# Otherwise, we print the canonical config type on stdout and succeed.
67
68# This file is supposed to be the same for all GNU packages
69# and recognize all the CPU types, system types and aliases
70# that are meaningful with *any* GNU software.
71# Each package is responsible for reporting which valid configurations
72# it does not support.  The user should be able to distinguish
73# a failure to support a valid configuration from a meaningless
74# configuration.
75
76# The goal of this file is to map all the various variations of a given
77# machine specification into a single specification in the form:
78#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
79# or in some cases, the newer four-part form:
80#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
81# It is wrong to echo any other type of specification.
