Script to generate ruby sinatra application skeleton. It adds: basic directory tree; boot file with requires and STDOUT logger; default controller; bundler dependencies; nginx/passenger configuration files; rake start task. How to use: ./sinatra_generator.sh application_name && cd application_name && rake start
