There are in fact a whole host of these special variables: $0, $1, $2,
... . As Mark said, the first of these is the path to the app. The later
ones are the arguments to the app, e.g.:

your.app --foo bar --baz

would give you:

$0 = your.app
$1 = --foo
$2 = bar
$3 = --baz

To find out how many arguments you have, there is the special variable $#
