[erlang-questions] Redirecting stdout in erlang

[SurferJeff]

Is that how it works?  One would implement an io_server process, and then 
call erlang:group_leader(MyIoServer, self()) or the like?
 
If so, that's great!  But, I found nothing in the group_leader 
documentation nor the io protocol documentation linked to below that 
describes these details.  I thought one would call 
erlang:group_leader(AnyOtherPid, self()) or the like, and self() would 
effectively inherit stdin and stdout from AnyOtherPid.
