Since Adam McCrea has introduced his solution for simplifying HTML mockups over on the EdgeCase blog, I thought I would take the time to reintroduce my own: Serve.
Based on my HAML server for web designers article, I've created a small gem "serve" which makes it extremely easy for a Web Designer to get up and running with Haml and Sass.
I have a script named serve in my bin directory that let's me quickly startup a Webrick server in any directory. This is handy for serving HTML mockups or other files. Today, updated it to work with.
