+			 * Initialize Salmanoff's Manager classes first.
+			 * Manager classes' initialization is synchronous in nature, so we
+			 * don't need the minds to be running to initialize them.
+			 *
+			 * Then we initialize the Minds. Minds are asynchronous and they
+			 * call upon the async methods of the Manager classes. Device
+			 * attachment is actually Mind specific and not Smo-global
+			 *
+			 * It is arguable whether library loading is Mind specific or
+			 * Smo-global. You could argue that libraries should be loaded and
+			 * unloaded dynamically as-needed by the bodies and worlds of
+			 * particular Minds. You could also argue that we should load all
+			 * libraries at startup and unload them at shutdown.
+			 *
+			 * The latter is cleaner and more resource-respecting. The former is
+			 * easier to implement.
