Script to keep a history of changes done to /etc/

[Petter Reinholdtsen <pere@hungry.com>]

One of the script I have written as part of my work here at the
University of Oslo is a little fragment to maintain a history of the
changes done in /etc/.  I believe this script can be useful for all
installations, and was allowed to release it as GPL.  Here is the
script.  It require a minor rewrite to go into the debian-edu-config
package.  I'll try to find time to do that unless someone beats me to
it.  Anyone want to improve it?

Share and enjoy.
