The supervisor behaviour encapsulates process creation and linking.  All
you need to do is specify the process to create in a child specification:

     {Id, StartFunc, Restart, Shutdown, Type, Modules}

So just:

     init([]) ->
          StartMod = sender_worker,
          ChildSpec = {StartMod, {StartMod, boot_send, []}, temporary, 4,
worker, [StartMod]},
          {ok, {{one_for_one, 1, 5}, [ChildSpec]}}.
