-%%% Purpose : SSL broker
-
--module(ssl_broker).
--behaviour(gen_server).
-
-%% This module implements brokers for ssl. A broker is either a connector, 
-%% an acceptor, or a listener. All brokers are children to ssl_broker_sup,
-%% to which they are linked. Each broker is also linked to ssl_server, and
-%% to its client.
-%%
-%% The purpose of the broker is to set up SSL connections through calls to
-%% ssl_server and gen_tcp. All control information goes to the server,
-%% while all data is exchanged directly between gen_tcp and the port program
-%% of the ssl_server.
-%%
-%% A broker is created by a call to start_broker/3 (do *not* use start_link/4
-%% - it is for ssl_broker_sup to call that one), and then call listen/3, 
-%% accept/4, or connect/5. 
-%%
-%% The following table shows all functions dependency on status, active 
-%% mode etc.
-%%
-%% Permitted status transitions: 
-%%
-%%		nil	->	open 
-%%		open	->	closing | closed (termination)
-%%		closing	->	closed (termination)
-%%
-%% We are rather sloppy about nil, and consider open/closing == !closed,
-%% open/closing/closed === any  etc.
-%%
-%%
-%%	function/	 valid			mode		new
-%%	message		 status					state
-%%								
-%%	calls							
-%%	-----							
-%%	recv		 open			passive		ditto
-%%	send		 open			any		ditto
-%%	transport_accept nil			any		open
-%%      ssl_accept       nil                    any             open
-%%	connect		 nil			any		open
-%%	listen		 nil			any		open
-%%	peername	 open/closing		any		ditto
-%%	setopts		 open/closing		any		ditto

-%%	inhibit		 any			any		ditto

-%%	tcp_closed	 open | closing		active		closing
-%%	tcp_error	 open | closing		active		closing
-%%
-%%	(1) We just terminate.
-%%
-%% TODO
-%%
-%% XXX Timeouts are not checked (integer or infinity).
-%%
-%% XXX The collector thing is not gen_server compliant.
-%%
-%% NOTE: There are three different "modes": (a) passive or active mode,
-%% specified as {active, bool()}, and (b) list or binary mode, specified 
-%% as {mode, list | binary}, and (c) encrypted or clear mode
