Crossplatform (Windows, Linux, Mac OS X, FreeBSD) python module to access power capabilities of the system.

• Power source type: AC, Battery or UPS
• Battery warning level: no warning (None), less than 22% of battery (Early), less than 10min (Final)
• Time remaining estimate
• Fault tolerant: if for some reason power capabilities cannot be extracted, falls back to AC
• Support for multiple batteries
• Power changes can be observed (Mac OS X only for now)
• Very easy to extend to support new features or new systems

Until we expand the documentation please have a look in power/tests.py
