So, INSTALL refers to an installtion and an upgrade script (install.sh
and upgrade.sh respectively).  Where are they?

I just extracted the sets by hand anyway, but it seems that it
would confuse a first-time user.  Unless I'm horribly misreading
the INSTALL document, it says to run these scripts, but never says
where to obtain them (following the diskless instructions), and I 
don't see them on the FTP site anywhere.
