    # 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.
    
    # 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.
