I was playing around with Gollum and when I booted it up, I was greeted with a great log message:

== Sinatra/1.2.6 has taken the stage on 4567 for development with backup from Thin
>> Thin web server (v1.3.1 codename Triple Espresso)
>> Maximum connections set to 1024
>> Listening on 0.0.0.0:4567, CTRL+C to stop
^C>> Stopping ...

== Sinatra has ended his set (crowd applauds)

Wait! That’s Triple Espresso! I better update my Thin – it’s still on v.1.2.11 codename Bat-Shit Crazy.
