Hello Gerd,

Thank you for your detailed reply. I think I'll try to use your code in
our project.

I've not yet read all your documentation but I've started to look at
your code to see what we would need.

The ocamlrpcgen approach is very seducing. By using a .xdr file and
generating only the _aux modules, it would allow us to easily add or
change the format of our network messages. Plus it would provide a basis
for message specification and interoperability.

The aux module would then be used for packing/unpacking into O'Caml

>From what I have understood of your explanation, I should do:
 O'Caml value -> xdr_value -> string       for encoding 
and the reverse for decoding.

Looking at your sources, it seems I need:

rpc-0.3.3/src/generator/*  (whole directory)
rpc-0.3.3/src/rpc/  (we are using ocaml 3.04 and up)

Do you see anything blatantly missing?

I'll add a file ORIGIN pointing to your web site for RPC. Do you want me
to provide any email or mail address?
