Creates OS X .app package from a script.

Lets say we have script HelloWorld.sh:

#!/usr/bin/env bash
osascript -e 'display notification "Hello, World!" with title "Hey!"'

Now use script2app:

./script2app.rb HelloWorld.sh

Here we are. Now we have HelloWorld.sh:

open HelloWorld.app

Note that you don't have to make script executable. Script will do it for you.
