appify v3.0.1 for Mac OS X - http://mths.be/appify
Creates the simplest possible Mac app from a shell script.

Appify takes a shell script as its first argument:

    `basename "$0"` my-script.sh

Note that you cannot rename appified apps. If you want to give your app
a custom name, use the second argument:

    `basename "$0"` my-script.sh "My App"
