Overview

rails g dragonruby:mount underwater

Writes the one line that is easy to get subtly wrong: the mount has to point at a directory outside public/, and the game is linked with a trailing slash.

The namespace is declared rather than derived. Rails would camelize "dragonruby" to Dragonruby and look for that constant; the gem's module is DragonRuby, so the two are spelled out separately here.
