We agreed that to add a liblauncher to facilitate the `main` entry point. However, as I mentioned before, this is really a depends on situation and should be answered at link time. One obvious question is how do we deliver javaw(with WinMain) symbol for Windows?

Also all the tunable configuration at build time such as MAIN_CLASS and JAVA_ARGS for an executable? Or are we simply thinking of `java` here?
