Brian,

Go to www.gerry.vanagon.com

Look through the file archives and see if you can find an article on how
to do this.

If that doesn't work search gerry's e-mail archives.  Just set the time
frame for the last year.  This has been discussed extensively during
that time.  The search will go much faster.   I've never done this, but
know I have read detailed discussions of how to do it on the list in the
last year.
