## What it is
pythonbrew is a command-line Python environment manager written in Go that installs multiple Python versions and switches between them, with virtualenv support. Inspired by perlbrew and rvm, it is no longer under active development.

## Use cases
- install multiple python versions on one machine
- switch python version per shell or permanently
- manage virtualenvs for different python versions
- list installable python versions
- uninstall old python versions

## When to choose
- you need a lightweight Go-based alternative to pyenv on legacy systems
- you already use pythonbrew in existing scripts

## When to avoid
- starting a new project - the project is unmaintained
- you want active support for new Python releases - use pyenv instead

## Facets
