I don't have my home machine back up and running (since moving to
Australia), so I've been putting off this post.  Since it looks like
it'll be another couple months before I can buy the extra parts I
need, I'll have to post what I can from memory.

There was an article published in Dr. Dobb's Journal at least two
years ago about an auto-routing algorithm called "AI".  There was an
accompanying program which I ftp'd from somewhere.  It took a text
input language and generated a binary board map which could then be
viewed on an IBM PC or printed on an HP laser printer.

I wrote a PostScript back end for the package so I could use the
printers I had access to.

This package only supported 2 layer boards (I tried very hard to get
it to generate single layer boards, but without much success.)

The README that came with the code indicated that the author was
interested in producing all sorts of enhancements, but I've not seen
any followups.
