I can't find it now, but I did have a routine that would use $0 and
`pwd` and put them together to find a script's directory. I didn't
just concatenate, I also scanned the start of $0 for "../" instances
and used them to remove the last level or levels of the working
directory, then concatenated them. If I can find it, I'll post it.
