Alter Joomla sh404sef extension for glossary component

I have an sh404 sef entension for Joomla's Glossary component that works but needs updating a bit to create better title meta tags and also to auto create description and keyword meta tags based on the content of the Glossary entry. The latter part may be done in the Glossary component itself if it's easier? You can either use your own installation of Joomla 1.5 and install the Glossary component with my sef extension, or I can let you edit files on my server.
