    43 # a failure to support a valid configuration from a meaningless
    44 # configuration.

    47 # machine specification into a single specification in the form:

    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.
