    37 # Configuration subroutine to validate and canonicalize a configuration type.
    38 # Supply the specified configuration type as an argument.
    39 # If it is invalid, we print an error message on stderr and exit with code 1.
    40 # Otherwise, we print the canonical config type on stdout and succeed.

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

    45 # Each package is responsible for reporting which valid configurations
    46 # it does not support.  The user should be able to distinguish
    47 # a failure to support a valid configuration from a meaningless
    48 # configuration.
    49 
    50 # The goal of this file is to map all the various variations of a given
    51 # machine specification into a single specification in the form:
    52 #	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
    53 # or in some cases, the newer four-part form:
    54 #	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
    55 # It is wrong to echo any other type of specification.
