Answer 1

There are a few options, detailed in the Sinatra FAQ. The simplest appears to be to use shotgun, which you can install and invoke as follows:

$ sudo gem install shotgun
$ shotgun myapp.rb

or if you use define your app by inheriting from Sinatra::Base and use a config.ru file:

$ shotgun config.ru -p 4567
