Is it possible to create nodes (ie: [node1@localhost, node2@localhost]) programmatically?

If you had a fragmented Mnesia database running across 10 nodes for example, are you forced to start 10 erl consoles from the shell?

Is there a way to manage (start and stop) nodes from an erlang process? Something like the following?

spawn_node(Name, Host) -> {ok, Node} | {error, Reason}

then you could do:

{ok, _Node} = spawn_node(node1, net_adm:localhost()),
pong = net_adm:ping(node1@localhost),
rpc:call(node1@localhost, mnesia, start, []).

Thanks,
Jake
