 # 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:

 # 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.
