Python script to generate plists into a Settings.bundle for all licenses of open source software you are using in your application.

acknowledgements.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

# Setup
#
# 1. Create a directory to hold your 3rd party code, each module in it's own named directory (i.e. 3rdParty/AFNetworking).
# 2. Make sure under the module directory there is the LICENSE file (file must have LICENSE all uppercase in the name)
# 3. In your Settings.bundle add a row to the Root.plist with: Type=PSChildPaneSpecifier, Filename=Acknowledgements, Name=Acknowledgements.
# 4. In the script below,
#     - set the settingsDir to the directory where the Settings.bundle resides (if not source root),
#     - set the licenseDirs to the directory(s) where you place your 3rd party modules (i.e. Pods)
# 5. Add a build script to run this python script just after Target Dependancies.

Made able to handle any license file that contains LICENSE in the name. Found this was needed for some CocoaPods.
