Right now security releases are a pain in the butt because we have to stop halfway through, apply a bunch of patches, then resume building.
Right now my idea is to add a --patch-dir option to make-release so it can have a directory of patch files to apply. The directory structure could look something like:
./core/T1234.patch ./skins/monobook/T4321.patch ./extensions/Example/T9876.patch
