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

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

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

     44 # Each package is responsible for reporting which valid configurations
     45 # it does not support.  The user should be able to distinguish
     46 # a failure to support a valid configuration from a meaningless
     47 # configuration.
     48 
     49 # The goal of this file is to map all the various variations of a given
     50 # machine specification into a single specification in the form:
     51 #	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
     52 # or in some cases, the newer four-part form:
     53 #	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
     54 # It is wrong to echo any other type of specification.
