Just a quick note to let everyone know that we've begun work on the inremental backup component that should make it easier to get course updates on Offline Moodle.

I've added a few notes to the wiki at
http://docs.moodle.org/en/Development:Offline_Moodle:_Incremental_Backups

We've also resorted to private mails to discuss the work and this obviously means no one else to can get involved. So to reverse this I thought I'd continue these discussions out in the open.

So here goes.

Dan, Matt, just wondering if we could have a few notes on the wiki about how to get the incremental backup stuff working. I've written a very short paragraph on how to generate incremental backups. But you've also created a couple of files to help the offline client to easily get the incremental from the server.

The files are get_incremental.php and send_incremental.php

When looking at the files I wondered if I should call them directly or if there is an admin menu or other file I should start from. Just little things like that so it's easier when I go in to test it because I'll know enough about how things should be working.

Related to this is that there are some guid tables that must be generated but mysql won't generate them. I know this will be addressed in time but they seem to be relevant particularly for these two files. Is this case?
