After re-reading that section more closely, I realize that I understand what it's saying; the part that I'm unsure about is how to actually go about implementing the drracket:language:language<%> interface. It would be nice if a small example was shown (like the examples shown when implementing a reader language). I am also unsure of where this implementation should go in my language directory: should it be in its own file? in the same file as the language module? The documentation suggests that I might be interested in the predefined simple implementation of the interface, drracket:language:simple-module-based-language%, and I think that is what I am looking for, but again there is the question of where I should be using this in my language implementation.
