Can someone tell me the syntax of the undocumented multicast options?
I thought I had figured it out but I still can't make it happy.  I was
trying this:

1> gen_udp:open(9875, [{add_membership, {{ip,{224,2,127,254}},{ip,{192,197,189,3}}}}]).
** exited: badarg **

... but obviously that's not it.  :(
