Yes, that's correct. So $0 is actually global variable named "0".

Well, you were right and wrong. ;) If you run that script (or a ruby
script) from the directory where it lives at, you get just the filename
in $0, since the base path is '.'; but cd .. and run it, and then
you'll get a full path. Confusing? ;)
