If you are like me you have bookmarked and read this article about 100 times in your life Creating Static Sites in Ruby with Rack.
I have a script that did this for me and I showed a friend this morning.
He challenged me to put it on-line in less than 10 minutes... I did.
Big thanks to Marshall Huss for putting the article together.
If you use Heroku you should download his app Nezumi. It's all kinds of awesome and costs less than a Pumpkin Spiced Latte.
