# cocos2d template installer script
# Author: Dominik Hadl (based on original script made by Stuart Carnie and Ricardo Quesada)
# Date: November 2013
# Description: This script installs cocos2d project templates to the Xcode templates directory, so they can be used within Xcode.
# TODO: 
# * Create an error log, if there were any errors during installation
# * Better handle errors on rsync
# * Add more colors... Yay!
