Overview

Execution context for classic style (top-level) applications. All DSL methods executed on main are delegated to this class.

The Application class should not be subclassed, unless you want to inherit all settings, routes, handlers, and error pages from the top-level. Subclassing Sinatra::Base is highly recommended for modular applications.
