Re: [Caml-list] [ANN] libbin_prot, php-bin_prot, ppx_bin_prot_interop

Hi Andre,

This is really cool! Just a few days ago someone asked me if we could
talk to a RPC server from C, so it looks like we could use libbin_prot
right now.

BTW, I've submitted a PR for the 1.0+beta1 of jbuilder yesterday, so
it should reach opam soon.
