+// Initializers are a way to register your object to be initialized at startup time.
+// They're a good way to have global variables without worrying about dependent
+// constructors being called. They also make it so init code doesn't depend on the
+// global objects it's initializing.
+
+// To use initializers, just use REGISTER_INITIALIZER to register your global variable like this:
+// class SomeClass {....}
+// SomeClass *g_pSomeClassSingleton = NULL;
+// REGISTER_INITIALIZER(SomeClass, &g_pSomeClassSingleton);
