    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.

    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.
