If you want a _portable_ solution, however... it gets harder.

Because the Mac doesn't really have a notion of "current" directory, it's
convenient to map "where the script is" to current directory. So "where the
script is" is "where we are" on a Mac. That's nice. Unfortunately in other
Perls, this won't work; the current directory is generally _not_ where the
script is.

If a script starts with #!...perl  AND the script is on Unix AND the script
is on your path or named by an absolute pathname, then $0 will contain the
full path to the script.

If the script is called by a relative pathname, then $0 contains that
relative path (and you have to figure out the location by where it is in
terms of the current directory.)
