Staff is a tool that helps your websites stand up. It's a port of the excelent Backbone.JS project by Jeremy Ashkenas from Document Cloud.
Back when I worked at Document Cloud with Jeremy, the code that was to eventually become backbone really excited me. Since then I've grown fond of vanilla ES5 APIs and wanted a version of backbone that was standalone and more like plain JavaScript.
This is a work in progress of that port.
