Hi Vincent,

"...I'm finding things a little difficult to relearn. I can't
find the manual after several years."

I'm in the process of updating the manual a bit, but there's
a passable one (automagically generated from the same source as
the paper manual) at

http://www.projectpluto.com/manual/page01.htm

Might come in handy from time to time... though as I wrote,
it's in need of an update.
