The initial module can be any module path. For example, to write a
module in the language containing everything from DrScheme's "Pretty
Big" language level, do this:

  (module m (lib "plt-pretty-big.ss" "lang") ...)

For Typed Scheme (a language available through PLaneT):

  (module m (planet "typed-scheme.ss" ("plt" "typed-scheme.plt" 1)) ...)

For the module named 'mylang' in the "mylang.ss" file in the same
directory, do this:

  (module m "mylang.ss" ...)

And so on.
