This is where we store our common assets, i.e. stylesheets, javascript, and images.
We use this to serve static assets to our applications. The assets themselves are generated using our styleguide. Once changes are made to the styleguide you can push the generated css into this repository. All the applications that link to postcode_main.css will pull in the new styles. Easy!
In your application point your css, js, images to the hosted version of the files. This is setup as a Heroku app:
So to use the main css file in your app do this:
<link href='http://pobox.herokuapp.com/css/postcode_main.css' rel='stylesheet' type='text/css'>
Or the PostCode image:
<img src="http://pobox.herokuapp.com/images/postcode_logo_blue.png">
