How do I build a Jonathan personality?

[Per Christian Nodtvedt]

Hi.   I need a very lightweigth middleware, and the two existing Jonathan personalities are too big.  The project I'm working on has therefore set out to build a personality on top of Jonathan.   Where can I find documentation on how to make a Jonathan personality on the web?  If this kind of document does not exist, where can I find a tutorial on using Jonathan without the David- or Jeremie personalities?  (it should be possible to send dummy tcp-segments, or am I completely in the dark now?)   I have attemted to read the source code, but I end up running in circles trying to figure out how to make Connections, Sessions, Session_Highs and Session_Lows in the TcpIpProtocol.  Any feedback would be greatly appreciated.   Regards, Per Christian Nodtvedt
