#I created this script for the simple reason that is very annoying to me extracting and moving the resources 
#to my project directory when i work with Android
#So, this script simply extract all the files from its current directory and merge them in the destination directory

#TODO and nice to have for the future:
#-Support for the sorce directory
#-Option to decide whether to override or not the resources
#-Renaming options? Like adding ic_ at the beginning? Maybe
