Buried in the depths of our code base (.NET house) has been a single
Perl script, hacked together by an ex-college one afternoon to

checked into source control, and the first (and last) piece of Perl
has left source control. The new version is just as quick and dirty as
the old, but at least can be run on any of our machines. As a matter
of general interest, before and after versions below:
