This category lists code that does not conform to any standard plugin type. It is also for plugins which don't yet meet all the different standards.
It requires special installation, and sometimes even needs hacks to core.
Plugins in this category are excluded from automatic updates. It is more likely this code will break when you upgrade Moodle, so we do not recommend installing it unless you have Moodle developers on hand to help maintain it.
