[erlang-questions] RPC module and erlang:group_leader/0/2 usage

[Zabrane Mickael]

Hi guys,

I'm digging a bit inside the "rpc.erl" module.

I found calls to "group_leader/0/2" almost everywhere (rpc:call, rpc:cast, rpc:eval_everywhere etc).

What's the purpose of using "group_leader" in this module?
Thanks in advance.

Regards,
Zabrane

It'll make io:formats show up on the calling node
