Create new glossaries from my Palm files

The out-of-the-box usefulness of ITM is severely limited by its inability to create a new glossary by scanning my Palm files.

It's nice that the importer can create new glossaries from text files, etc., but how can I easily convert all my Palm .pdb files into text files?

I would like ITM to scan my Datebook and my Memopad .pdb files and create a glossary from them.

Any suggestions?

Thanks.
