   36 # If it is invalid, we print an error message on stderr and exit with code 1.
   37 # Otherwise, we print the canonical config type on stdout and succeed.

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

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