Pip is the Python package installer. It integrates with virtualenv, doesn't do partial installs, can save package state for replaying, can install from non-egg sources, and can install from version control repositories.

This is the support package for the PEP 427 wheel version of the package, required for using pip inside a virtual environment.

This is the Python 2.7 version of the package, the last version of pip supporting Python 2.7.
