+         *
+         * The purpose of this factory is two-fold. Firstly, it is a good starting point for new plan factories; to use
+         * it as such, perform a
+
+         * \c svn copy include/NullPlanFactory.h include/YourPlanFactory.h\n
+         * \c svn copy src/NullPlanFactory.cpp src/YourPlanFactory.cpp
+         *
+         * Remember to
+         *  - Adjust the include guards
+         *  - Adjust the string returned by get_name()
+         *  - Add a line in PlanFactoryLibrary.cpp to create an instance of the new factory in the library's
+         *    constructor; otherwise, it won't be accessible via the configuration file.
+         *
+         * And secondly, it is a debugging tool. Change the configuration file to use this AI factory for a certain
+         * AI_INDEX to have said group do... nothing (e.g. to measure performance differences).
