This is a build plugin for Meteor 1.2+. It uses autoprefixer to automagically add vendor-specific prefixes to your CSS files.
Install using Meteor's package management system:
> meteor add seba:autoprefixWithout any additional configuration after installation, this package automatically finds all .css files in your project, compiles them with autoprefixer, and includes the resulting CSS in the application bundle that Meteor sends to the client. The files can be anywhere in your project.
