Database files, file format, and source code

[sadffffff]

I'm looking to write a program that works with the rockbox database. So I would like to know how to work with these files. first, where are they? I assume that the files in .rockbox/database_#.tcd are the actual generated database files. And I need to know the format of these files, since i see they're not completely readable in wordpad. Is this info documented in the wiki/manual somewhere?

Later on, I plan of porting my program to a plugin for rockbox with added features, and for that part, the Database source would be very usefull. (If the database format is undocumented I may need the source for the first part aswell.) I assume I can get the source off the SVN from what I've read?

I think its all in /apps/tagcache.c and .h.
