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

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

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

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