Thanks for the link. The site doesn't describe the technique they use though -- it looks like a simple file bundler that works by scanning the source for require statements.
I don't want to generate obscured or encrypted packages. I want people to be able to read and modify my code.
The touch+find technique given above is actually very simple -- two Unix commands which I haven't even bothered to make a script for. The only down-side is that when packaging modules with lots of autoloads, you have to be sure your testing every execution path.
