## What it is
A plugin framework for CSS preprocessing in Node.js, built on the css parser, enabling AST-based CSS transformations like vendor prefixing, custom properties, and asset inlining. It is effectively unmaintained, with no material changes in a decade and an explicit recommendation to use more modern alternatives.

## Use cases
- programmatically transform css in nodejs
- build custom css preprocessing plugins
- automate vendor prefixing in css
- inline images as data uris in css
- resolve calc expressions in stylesheets

## When to choose
- maintaining a legacy build pipeline already using rework plugins
- you need a minimal, simple css AST transformation framework

## When to avoid
- starting a new css preprocessing project
- you need actively maintained tooling or bug fixes
- modern alternatives like postcss would fit better
