Shield - A collection of common Bukkit protection plugin API
Author: Malikk
Version Beta 1.2

Shield is an API, bridging the gap between the many region protection plugins and the common plugin. Through Shield, plugin developers can easily access a variety of methods, without hooking a specific protection plugin, and have them applied universally. Hours of work adding support for a small handful of protection plugins is a thing of the past. A lot of work has been put into making Shield as easy to use as possible, so all of the api can be found in a single interface, clearly labeled and clearly documented automatically as soon as you've configured your build path.
To develop with Shield, all you have to do is download the jar and add it to your project's build path. For help hooking in Shield, check out the Shield Wiki.
Provided you are using a protection plugin supported by Shield and a plugin using its API, all you have to do is download Shield and drop it into your plugins folder. If you are using multiple protection plugins you can set their priorities in the config file.
and soon many more!
