Hi Micheal - sorry it took so long to respond. The plugin is way outdated - I haven't touched it in some time. I don't have any documentation on it and at last check, it didn't work with the latest few generations of Sage. If you still want it, I can email it to you (1.5 MB or so in size), but I am not sure if it will be useful to you. Send me an email at
spamgerm@gmail.com and I'll respond with the file!
