# Configuration subroutine to validate and canonicalize a configuration type.

# Supply the specified configuration type as an argument.

# If it is invalid, we print an error message on stderr and exit with code 1.

# Otherwise, we print the canonical config type on stdout and succeed.

# You can get the latest version of this script from:

# http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub

# This file is supposed to be the same for all GNU packages

# and recognize all the CPU types, system types and aliases

# that are meaningful with *any* GNU software.

# Each package is responsible for reporting which valid configurations

# it does not support. The user should be able to distinguish

# a failure to support a valid configuration from a meaningless

# configuration.

# The goal of this file is to map all the various variations of a given

# machine specification into a single specification in the form:

# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM

# or in some cases, the newer four-part form:

# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM

# It is wrong to echo any other type of specification.
