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

   38 # Otherwise, we print the canonical config type on stdout and succeed.

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

   54 # or in some cases, the newer four-part form:
   55 #   CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
