[REBOL] Re: Writing a protocol -- a mini intro

Applause to Holger for the additional the clarifications and deeper information on port handlers.

I recommended starting out with pass-thru ports for pedagogical reasons, because you can define each of the protocol phases and see them in action-- which lets you see the engine operation, so to speak. :) As the custom protocol writer gets deeper into it all, deciding what port paradigm is most fitting helps determine the appropriate port type from those outlined by Mr. Kruse. Getting the whole port mechanism to do most of the work for you is the name of the game. -jeff
