That's good to know.  Is it a recent version, though?  IE., 8-bit clean and
multiuser-capable?  I like screen as a training tool, honestly.  It's like
DoubleVision without the bugs or pricetag.  I use the umask's for screens,
have people in as read-only on all screens, and totally disable them from
getting at my root session screens.  So the multiuser functionality is kind
of a must for me.  Then again, I have a linux box.  :)  But it would be
nice to put on a few SCO boxen I use.

Screen has been around since at least '90, when it was hosted at orst.edu.
Actually, if Brian had done his homework (please don't deliver the moon,
I can't afford the shipping!), he'd know that screen -WAY- predates its
association with GNU and the FSF.  From ChangeLog:

*****
3.1.1
------

Screen is now under the GNU copyleft license. See file COPYING.
*****

A later version number also saw the replacement of CHANGES with ChangeLog
to make it more GNU-ish after GNU got hold of it.  This was -NOT-
originally FSF software.

There aren't any references to what licensing was before then, but it was
definitely hosted off ftp.cs.orst.edu for -years- before it even touched
upon going GPL.  I think (and this is -real- hazy) that it was actually
developed at Oregon State, not just hosted there.  Seem to remember that
from back in the day, but try finding sources to versions that old in 5
minutes...

Don't know when mscreen came out, don't care.  Hell, window(1) [which I
used before I found screen, and which I think preceeded it) probably beats
up mscreen.  Both were on the first BSD 4.3 Tahoe machine I was ever on.
Window was pretty cool in that it let you have window dividers and change
the window sizes at will.  As long as you did a 'resize' you were fine.
Used to have 3 windows on one 25 line terminal all at once.  I'm not sure I
ever found a way to make screen do that particular thing.  Possibly, but if
so I've forgotten how.

If mscreen had the same love and craftsmanship poured into it that MMDF[2]
did, NO THANK YOU.  :)
