This, and a thousand and one similar items, are in the great archives that
Mark Deloura maintains for the group.

For all those people with questions starting with, "Where do I find ...",
"What is the number for ...", "Which unis do work in ...", and so on,
you can get some great info from the archives.

Since I (as one) had some trouble first figuring out how to do this,
I have posted below a "captured" session in which I get the README files
from the FAQ. (These tell you which files to ftp for various products.)

Oh, if you find that the info you want is not in the archives, or is
badly out of date, then doing the footwork and posting the results
is usually appreciated by the group. But watch out--the archives are
so big you might miss a few tunnels if you're not careful!

(I know this is old stuff, but lots of readers of sci-vw are new, and 
I hope a post of this info will avoid them being disappointed when
everyone else ignores them (for not looking in the archives first).
Maybe the reduction in "Where do I get ..." postings will partly compensate
for my eating up bandwidth recently. <grin>)

Comments by me are in [ ..  .. ], and are not part of the session.

... and that's all there is to it! When you know what files you need,
you can go back for them. Don't forget the thing's like a big labyrinth when
you first walk in, so you might need to look through the directories to
find what you want.

Hope this is of help to some.

John
