"""Central wrapper for all old entrypoints.
Historically pip has had several entrypoints defined. Because of issues
arising from PATH, sys.path, multiple Pythons, their interactions, and most
of them having a pip installed, users suffer every time an entrypoint gets
moved.
To alleviate this pain, and provide a mechanism for warning users and
directing them to an appropriate place for help, we now define all of
our old entrypoints as wrappers for the current one.
