Gnus: a mkgnus script

[Manoj Srivastava <srivasta@datasync.com>]

Hi,

	I love Gnus; and have been on the ding mailing list since way
 back when (before I came to Debian, I think). And so I loved it when
 it was packaged for Debian -- but the version packages was 5.6.27, in
 a week or so, we are at 5.6.31! Gnus development has ever been like
 this. 

	So what I did was to grab the debian directory created by
 Michael Alan Dorman <mdorman@debian.org> (thanks, Michael), add to
 the changelog as goven below, and stash the tar file in
 /usr/local/share/emacs/site-lisp/ 

	I wrote the script below, called mkgnus; and now, I can fire
 of mkgnus; which downloades the latest version from the upstream site
 using wget; untars it, untars the debian files, edits  the changelog
 to put in the version number, optionally copies custom files in (not
 needed any more); and creats a .deb file. All this with no human
 intervention. I load the .deb file. and away I go. No fuss. 

	I though I would share this with people. Do you think that
 this deserves to be a separate package? 

	I hope this proves useful to someone else as well.

The new changelog file (note the XXXX which shall be replaced by a
real version). The rest of the files were unchanged from theofficial
version.
