-client file_type

   Determines which client files to generate.  If you do not specify
   this argument, the compiler generates all client files.  The file
   types are as follows:

   none Does not generate client files.

   stub Generates only a client stub file.

   aux  Generates only a client auxiliary file.  A client auxiliary
        file is generated only if the interface contains any out-of-
        line or self-pointing types.

   all  Generates client stub and client auxiliary files.  This is the
        default and is the same as not specifying the -client argument.
