If you're not a fan of processing styles with a bundler, then you can use a task

runner instead (like Gulp), to process your CSS and generate your meta object(s).

**IMPORTANT NOTE**

This setup will only work once[this update](https://github.com/postcss/gulp-postcss/pull/150)

is released.

Until then, you could use the same idea outlined here with the[postcss](https://github.com/postcss/postcss)

package itself.
