"""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.
