I have been searching for two days, and I can't find anything in the knowledge base or forums that explains what the packager actually does. Obviously it creates some sort of package. But where does this package go? What does it contain? Is it a jar (that I can't seem to find)? Or is it that zip file of my source in the "Files" tab? And why the heck would I put my source there? Why won't git let me push a .jar file with (or instead of) my source files? Sigh.
