Sinatra is dead, as a dead fish. We killed him during abordage. Now we can investigate his body, see his guts, and check what he has inside. Since medieval, autopsy of dead corpse was the best way of learning how human body works. We will use the same technique, examinating Sinatra, to learn how to write better code. With its 1740 lines of code, this piece of software is great example of Ruby application. We will see what jewels are hiding in its chest, notice some good practice, but also we will take a look at bad and stinky parts. Since Aleksander's only commit to Sinatra was concerned documentation, he is the right person to lead the autopsy. He will look at Sinatra with the fresh eye. Konstanin Haase won't get any hurt (probably).
