Arnt rants and rambles on literate programming etc.

This is a placeholder.

I'm the next many months, I'm going to write long series of semirelated postings on source code documentation, covering the techniques I developed at Trolltech and extended for Archiveopteryx, what other people are doing and what I think of it all.

This is the introduction, which I mean to revise so it points to this and that. It points to nothing yet, there being nothing it could sensibly point to.
