Over less than a decade, I, one person, made a smallish Lisp dialect and documented it with a terse reference manual that doesn't repeat itself or pontificate all that much. It's formatted as one giant man page. If we render it to PDF, it's around 650 pages, with no table of contents or index. I am not a committee; I have no historic baggage from multiple base dialects. Shit that just popped into my head over a small span of time adds up to 650 pages already.
