| # Special case pip and setuptools to generate versioned wrappers |

| # The issue is that some projects (specifically, pip and setuptools) use |

| # 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into |
| # the wheel metadata at build time, and so if the wheel is installed with |
| # a *different* version of Python the entry points will be wrong. The |
| # correct fix for this is to enhance the metadata to be able to describe |
| # such versioned entry points, but that won't happen till Metadata 2.0 is |
| # available. |
| # In the meantime, projects using versioned entry points will either have |
| # incorrect versioned entry points, or they will not be able to distribute |
| # "universal" wheels (i.e., they will need a wheel per Python version). |
| # |
| # Because setuptools and pip are bundled with _ensurepip and virtualenv, |
| # we need to use universal wheels. So, as a stopgap until Metadata 2.0, we |
| # override the versioned entry points in the wheel and generate the |
| # correct ones. This code is purely a short-term measure until Metadata 2.0 |
| # is available. |
