 """Tool for manipulating naclports packages in python.
 
 This tool can be used to for working with naclports packages.
 It can also be incorporated into other tools that need to
 work with packages (e.g. 'update_mirror.py' uses it to iterate
 through all packages and mirror them on Google Cloud Storage).
