Import py26-pip-0.6.3 as wip/py-pip.

pip is a replacement for easy_install. It uses mostly the same
techniques for finding packages, so packages that were made
easy_installable should be pip-installable as well.

pip is meant to improve on easy_install. Some of the improvements:
    * All packages are downloaded before installation.
Partially-completed installation doesn't occur as a result.
    * Care is taken to present useful output on the console.
    * The reasons for actions are kept track of. For instance, if
a package is being installed, pip keeps track of why that package
was required.
    * Error messages should be useful.
    * The code is relatively concise and cohesive, making it easier
to use programmatically.
    * Packages don't have to be installed as egg archives, they can
be installed flat (while keeping the egg metadata).
    * Native support for other version control systems (Git, Mercurial
and Bazaar)
    * Uninstallation of packages.
    * Simple to define fixed sets of requirements and reliably
reproduce a set of packages.
