   Why not just upload .bz2 and have a script that steve can run
   automatically to convert to gzip after the upload. 
That was what I basically had in mind and it didn't work out.
The next best thing is to build the distributions network-topologically
closer to 
ftp.xemacs.org, which is what we're trying now[1].  Unfortunately,
cvs.xemacs.org doesn't have bzip2 installed, so I had to gzip the
21.2.5 tarballs.  Sigh.  If it looks like I'm making this up as I go
along, sigh, I am.  Please bear with me.
Footnotes: 
[1]  And it still took over 3 hours to make and upload a
distribution.  :-(
