I have tried to contact Marc to ask him to put a link on the client libraries page on this site,
but since he is not responding, i thought i would still tell the community.
Thanks Dennis. I am sorry, for not having answered. Your email ended up in the spam folder and I didn't see it.
Of course I have set a link to the library on the client library overview page:
