   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
   43 # and recognize all the CPU types, system types and aliases

   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.
