+// This file is compiled as part of the `odin.dll` file. It contains the
+// procs that `game.exe` will call, such as:
+//
+// game_init: Sets up the game state
+// game_update: Run once per frame
+// game_shutdown: Shuts down game and frees memory
+// game_memory: Run just before a hot reload, so game.exe has a pointer to the
+//		game's memory.
+// game_hot_reloaded: Run after a hot reload so that the `g_mem` global variable
+//		can be set to whatever pointer it was in the old DLL.
