[Paul Anderson <paul@geeky1.ebtech.net>]

Something to think about?  Here's the only chunk of source I've written,
if someone wants to help the idea, speak up.  I need to figure out what
format the package info should be stored in on the disk, and I need
someone to write a parser for it.  BTW, I'm giving serious thought to
installing Debian on my 386.(Which, AAMOF, will by the end of the year be
mounted inside a small submarine I'm building as a control computer)
TTYL!
