Enhances create-react-app to include support for stylus.

npm install create-react-app-stylus --save-dev

Replace your start and build scripts in your package.json.

"scripts": {
  "start": "react-scripts-with-stylus start path/to/main.styl",
  "build": "react-scripts-with-stylus build path/to/main.styl",
  "test": "react-scripts test --env=jsdom",
  "eject": "react-scripts eject"
},

This is configured to work off of one .styl file that will use @import to import all the rest of your css. As an example, if you have src/styles/app.styl, your start command will be react-scripts-with-stylus start src/styles/app.styl. Then in your index.js you will need to import './styles/app.css' to have create-react-app pull in your css. Make sure to add *.css to your .gitignore as it is now a build artifact.
