public abstract class AServerAgent
extends AServerPlugin

AServerAgent is an AServerPlugin derivative designed to work as an agent on behalf of AServer. It's sole purpose is to launch, shutdown, and otherwise control AServerPlugins to which AServer has no direct tie. It's particularly useful for packages with multiple AServerPlugins. AServer only needs to know about the one agent which manages all the worker plugins.
