+/**
+ * The Screeps Profiler is a library that helps to understand where your CPU is being spent in
+ * the game of Screeps.
+ * It works by monkey patching functions on the Global game object prototypes, with a function that
+ * record how long each function takes. The primary benefit of using this profiler is that you can
+ * get a clear picture of where your CPU is being used over time, and optimize some of the heavier functions.
+ * While it works best for players that heavily employ prototypes in their code, it should work
+ * to some degree for all players.
+ *
+ * Any modules that you use that modify the game's prototypes should be imported
+ * before you require the profiler.
+ *
+ * @see More information at https://github.com/gdborton/screeps-profiler
