Install libimobiledevice on Mac OS X

So you'd like to manage your iOS devices by command line?
You can use libimobiledevice tools for that.
Easy on Linux. Let's see how it is on Mac OS X.

You'll need to:
1. install Xcode
2. start Xcode and agree to it's license
3. install Xcode command line tools (Start Xcode, Go to Preferences -> Downloads tab)
4. install homebrew by this command (sudo password will be prompted)

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

5. run following

brew install -s --HEAD libimobiledevice ideviceinstaller

6. ready to go

That's all, folks. Just a little more steps than in GNU/Linux.

So Mac OS X can really be of use by people.
