How Should RoboJogger Be Packaged?

A question for anyone who cares to chime in. Tonight I created most of a build script for RoboJogger. In the past I have used tools like Launch4J and IzPack to make executables and installers for Java applications for Windows. I could do this for RoboJogger, if anyone prefers. In addition to just making the source available, would you prefer: 1) A zipped archive where the main class is in a jar (unzip and run with javaw -jar robojogger.jar), or 2) A zipped archive where the main class is in an exe (unzip and run robojogger.exe), or 3) An installer that is a jar (run installer with javaw -jar robojogger-installer.jar), or 4) An installer that is an exe (just run robojogger-installer.exe). For 3) and 4), you could also indicate whether you think the main class should be a jar or exe, if that matters to you. Or I could provide it several different ways. So if you care one way or another, let me know.

Hi Mate. I'm on a mac here and i would prefer a jar in all cases. It also has to be max java 1.6 to be usable for me.
