        # The problem is that even after compiling, webroot/WEB-INF/lib/ and
        # webroot/WEB-INF/classes/ are still unpopulated, so simply jarring it up
        # isn't good enough. Here we populate classes/ and lib/. To do so, we need
        # all of the things that webProject depends on, EXCEPT for winstone (ourself).
