# asdf-python
Python plugin for [asdf](https://github.com/asdf-vm/asdf) version manager
## Install
```
asdf plugin-add python https://github.com/tuvistavie/asdf-python.git
```
## Use
Check [asdf](https://github.com/asdf-vm/asdf) readme for instructions on how to install & manage versions of Python.
When installing Python using `asdf install`, you can pass custom configure options with the following env vars:
* `PYTHON_CONFIGURE_OPTIONS` - use only your configure options
* `PYTHON_EXTRA_CONFIGURE_OPTIONS` - append these configure options along with ones that this plugin already uses
