- Add Python site user base subdirectories to config and data
user-level paths if `site.ENABLE_USER_SITE` is True. One way to
disable these directory additions is to set the `PYTHONNOUSERSITE`
environment variable. These locations can be customized by setting
the `PYTHONUSERBASE` environment variable. ([242](https://github.com/jupyter/jupyter_core/pull/242))
