 requires Python 2.7. Apart from this issue, the strategy of using the
 system Python has been working well. George, what do you think? Is it
 possible to rewrite option parsing to be compatible with Python 2.6?

 Hm, implementation of (2) is not trivial. Refactoring Pyobfsproxy to
 support Python 2.6 means that we will have to rewrite the cli parsing
 logic (which is kinda hard because it uses argparse `subparsers`), replace
 `OrderedDicts` in the integration tests, and change any other 2.7
 constructs are lying around. Also, pyptlib is not meant to be ran in 2.6
 either.

 What happens if we ship a Python interpreter along with the bundles? How
 much will the bundle size increase?
