Deploying LWJGL applications on Mac & Windows

The LWJGL wiki has instructions for deploying on Windows as a .exe file, but I can't find anything about how to create a Mac OS X .app bundle.

I could handcraft an Info.plist and build the app myself, but I'd like to have the option of distributing the JRE with my app and I don't think I have the k开发者_开发百科now-how to do so.

Are there any generic Java app --> .app bundle helpers?

I believe Apple supports this function with an App called "Jar Bundler". It transforms a .jar file into a .app package.
