Re: [PATCH 10/16] rpcgen: define entrypoint for running new rpcgen impl

The new program takes the form rpcgen [--mode source|header|repr] \ [--header include] \ xdr-file output-file If '--mode' is not given it parses the XDR file but does not generate anything, which is useful as a syntax check. The 'source' mode gives the '.c' file content, while 'header' gives the '.h' file content. 'repr' gives a representation of the abstract syntax tree, mostly useful for debugging the parser. If '--header' is given, it is added as a local #include ".." statement in the output and is valid for either 'header' or 'source' modes. Either 'xdr-file' or 'output-file' can be omitted in which case they default to stdin/stdout respectively. This rpcgen program will directly include the 'config.h' header in its output.
