title: Given a podspec file, what do I then do to include it in my project?
body: <p><a href="https://github.com/AFNetworking/AFOAuth2Client#example-usage" rel="nofollow">AFOAuth2Client</a> has a podspec file, which leads me to think it supports Cocoapods. How do I include it in a project? There's normally a "how to install with Cocoapods" section but I don't see one.</p>
