I'm using OpenOffice-OODoc 2.026, with XML-Twig 1.303, it seems. At least, that's what I assume this line at the top of Twig.pm means:
# $Id: Twig_pm.slow,v 1.303 2006/05/26 08:07:14 mrodrigu Exp $
Seems like mine is a lot older than what the rest of you are using. I guess I should talk to my IT guys about upgrading it.
