Oh, I'm not suggesting _that_.  I just want to get over the hurdle of
adding documentation.  I've had a good number of people propose
documentation additions or new content, but none of it has happened,
because there's so many hoops to jump through.  I'm to the point where I
take plaintext from others and mark it up myself, and that's turning me
into a bottleneck.

Just having it on the web would be nice - I suspect a majority of the
usage comes from online reading, in any case.

Should be possible, as that's how Wikis work - tracking revisions.  I
guess I just cut this task out for myself.
