I've added `rackunit' to the "mz" distribution, since it's becoming common for developers of libraries in the "mz", "mr", and "dr" packages to include `rackunit'-based tests in a `test' submodule.
The GUI part of the "rackunit" collection is still in "plt" package. _________________________ Racket Developers list: http://lists.racket-lang.org/dev
