Modified version of http://mojo.codehaus.org/osxappbundle-maven-plugin/. "This plugin creates an Application Bundle for OS X containing all your project dependencies and the necessary metadata. The application bundle will be packaged in a zip-file, allowing you to build it on Linux or Windows and then unpack it as an application on OS X. If this plugin is run on a Mac OS X platform it will also create a DMG disk image containing the Application Bundle."
