This is cool, but it doesn't seem to good as good a job as AppZapper/AppCleaner/CleanMyMac when completely uninstalling something. I found a couple apps (esp those with preference pane entries) where there were some leftovers that the other cleaners would've caught. Regardless, it's cool to have an option for the command line.

What's wrong with rm -rf /Path/To/Application?

That doesn't remove all of the associated preferences, caches, and other stuff the application could have left around.
