   30 # Configuration subroutine to validate and canonicalize a configuration type.
   31 # Supply the specified configuration type as an argument.
   32 # If it is invalid, we print an error message on stderr and exit with code 1.
   33 # Otherwise, we print the canonical config type on stdout and succeed.

   38 # This file is supposed to be the same for all GNU packages

   41 # Each package is responsible for reporting which valid configurations
   42 # it does not support.  The user should be able to distinguish
   43 # a failure to support a valid configuration from a meaningless
   44 # configuration.
   45 
   46 # The goal of this file is to map all the various variations of a given
   47 # machine specification into a single specification in the form:
   48 #   CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
   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.
