looking for a minimalistic example of RPC

Hello,

Where can I find a minimalistic example of a client and server
using ocamlnet's RPC library?

I looked into the sources of ocamlnet in examples/rpc/finder
but the finder example uses netplex, so it is not really
a minimalistic example.

I am looking for something really trivial, for example:

A module A with function 'some_int ()' that returns
an int each time it is called.
A module B, client of A which would invoke the remote some_int
method provided by module A and get the result in a synchronous manner.
