    35 # Configuration subroutine to validate and canonicalize a configuration type.
    36 # Supply the specified configuration type as an argument.

    46 # Each package is responsible for reporting which valid configurations

    48 # a failure to support a valid configuration from a meaningless
    49 # configuration.

    51 # The goal of this file is to map all the various variations of a given
    52 # machine specification into a single specification in the form:
    53 #	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
    54 # or in some cases, the newer four-part form:
    55 #	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
    56 # It is wrong to echo any other type of specification.
