       * The project name will be used as the entry point name. When invoking
       * GWT's WebAppCreator, the entry point name will be passed in as the last
       * component in the module name. The WebAppCreator will use the last
       * component of the module name as the generated Eclipse project name, which
       * gives us the desired effect.

       * FIXME: The project name may not be a valid entry point name. We need to
       * scan the project name token-by-token, and translate its tokens into a
       * valid Java identifier name. Some examples:
       *
       * If the first token in the project name is a lower-case letter, then the
       * translated character should be made upper case.
       *
       * If the first token in the project name is a non-alpha character it should
       * be deleted in the translation.
