Re: Anyone else needing this U2 updater?

Yikes, that's very complicated, Harry! If you're adding your own stuff
to U2, I strongly recommend that you NOT call your U2 file
"XYWWWEB.U2". Name it something else -- say, HB.U2. Structure the file
this way:

;U2;; <== File ID at Top of File

Your U2 frames here [if you insist they come first]

MErge XYWWWEB.U2 here

Put more of your stuff *under* XYWWWEB.U2 if you like.
<== End of File

When you update U2, unzip the new XYWWWEB.U2 and other files into the
same directory as HB.U2. Then RUN UPDATEU2.PM (see below). This program
simply swaps the old XYWWWEB.U2 out of HB.U2 (or whatever you decide to
call it) and swaps in the new.

Note: Don't attempt to recast UPDATEU2.PM as a U2 frame. It won't work,
due to feedback loops.
