We are innocent users who don't know the administrator has freshened
emacs.  Or we are debian users who have done "apt-get upgrade" and
freshened 100s of packages...

Hmmm, I bet if I make the NEWS file one of the mailboxes tracked by
gnus, that would be an interesting way of being aware if it changed...

Wait, those 100s of packages also have their own change notes,
therefore why should emacs' be a special case that we want to read
more than the others?

Ok, never mind.

Marco sent this to me.  As it has a spam status rating of -37.7, it
must be good stuff.  Hence I will share it here.

You can download checkurls [1] version 0.5.0-alpha1 [2] [3], install
it, and put the following in your ~/.emacs:

  (shell-command "checkurl file_in_subdir_n_from_the_end:///usr/local/share/emacs:2:etc/NEWS &" "*checkurl*")

or

   checkurl file_in_subdir_n_from_the_end:///usr/local/share/emacs:2:etc/NEWS

in your ~/.profile.

This may send you and email a) the first time you run it, with the
full NEWS file, and b) each time you run it and the file is changed,
with a the differences from the previous version.

See `info checkurls' and `info checkurl' for more infos.

The URL can change depending on where you installed Emacs.

file_in_subdir_n_from_the_end://PATH:N:PATH2

This means the PATH2 file in the Nth subdir (counting from the end) in
the PATH directory.

So if you have

   marco@marc0host:~/web/marc0$ ls /usr/local/share/emacs/
   21.3.50  site-lisp
   marco@marc0host:~/web/marc0$ 

then

   file_in_subdir_n_from_the_end:///usr/local/share/emacs:2:etc/NEWS

will expand to

   /usr/local/share/emacs/21.3.50/etc/NEWS

And then in the future if you have

   marco@marc0host:~/web/marc0$ ls /usr/local/share/emacs/
   21.3.50  24.5.40 site-lisp
   marco@marc0host:~/web/marc0$ 

then

   file_in_subdir_n_from_the_end:///usr/local/share/emacs:2:etc/NEWS

will expand to

   /usr/local/share/emacs/24.5.40/etc/NEWS
