As part of my process for releasing a new version of Arq, I needed a way for my script to get the version of an app bundle.

So, I wrote a simple utility called appversion which prints the value for the CFBundleVersion key in an app’s Info.plist.

For example:

	appversion /Applications/iPhoto.app

yields:

	8.1
