Zhiqiang Fan a8a7c68990 print usage when no argument is specified for python3
When running just 'glance' under python3, we will get the error:
ERROR: 'Namespace' object has no attribute 'func'

This is because map() is used to decode sys.argv, but under Python3
it returns a map object which is an iterable. Some code later tries
to use this in a boolean context and it will always return True,
even if it's empty.

Python bindings to the OpenStack Images API

This is a client library for Glance built on the OpenStack Images API. It provides a Python API (the glanceclient module) and a command-line tool (glance). This library fully supports the v1 Images API, while support for the v2 API is in progress.

Development takes place via the usual OpenStack processes as outlined in the developer guide. The master repository is in Git.

See release notes and more at http://docs.openstack.org/developer/python-glanceclient/.
