+### `//maze <replace_node> [<seed>]`
+Generates a maze using replace_node as the walls and air as the paths. Uses [an algorithm of my own devising](https://starbeamrainbowlabs.com/blog/article.php?article=posts/070-Language-Review-Lua.html). It is guaranteed that you can get from every point to every other point in generated mazes, and there are no loops.
+
+A seed can optionally be provided, which will cause the same maze to be generated every time (otherwise `os.time()` is used to dynamically set the seed).

 ### `//multi <command_a> <command_b> <command_c> .....`
 Executes multi chat commands in sequence. Intended for _WorldEdit_ commands, but does work with others too. Don't forget a space between commands!
