Hi Warren!

I'm looking through my Downloads directory to try to clean it up
a bit. I found this:

        $ ls -l osutils.tar.gz
        -rw-rw-r-- 1 arnold arnold 101072 Nov 25  2012 osutils.tar.gz

It is the code for awk, grep, and libregex, released under the
GPL 2, from 2001.

If you don't already have it, you might want to put it in the archive
somewhere and also announce it on the list.

Thanks!

Arnold
