   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.

   45 # This file is supposed to be the same for all GNU packages
   46 # and recognize all the CPU types, system types and aliases
   47 # that are meaningful with *any* GNU software.
   48 # Each package is responsible for reporting which valid configurations
   49 # it does not support.  The user should be able to distinguish
   50 # a failure to support a valid configuration from a meaningless
   51 # configuration.
   52 
   53 # The goal of this file is to map all the various variations of a given
   54 # machine specification into a single specification in the form:
   55 #   CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
   56 # or in some cases, the newer four-part form:
   57 #   CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
   58 # It is wrong to echo any other type of specification.
