Perhaps I wasn't clear enough. I was thinking about a *complete* reference, of the type that would be considered definitive, if our (english language wikipedia) policies, practises, and software features implemented, weren't a moving target (as they very palpably are).
The argument about what a "short" wikipedia guides length would be is too close to an argument about how long a piece of string is...
About half the Wikipedia namespace and the whole Help namespace?
The real problem you'll come across is all the unwritten rules, precedent and tradition that govern most of what we do.
