How do you make a WordPress Theme part of the auto update check. I know you can plug in to the plugin auto updater, to add/remove plugins from the auto updater, but how do you do this with themes?
I tried digging through the Twenty Ten theme, but there is no code anywhere which defines how it auto updates, or registers it for auto update. Yet, it auto updates with WordPress.
Any help would be greatly appreciated.
EDIT: Should have specified, my theme is not in the WordPress repository. It will be distributed separately.
