 //! ## Consistent Behaviour
 //! `webbrowser` defines consistent behaviour on all platforms as follows:
 //! * **Non-Blocking** for GUI based browsers (e.g. Firefox, Chrome etc.), while **Blocking** for text based browser (e.g. lynx etc.)
 //! * **Suppressed output** by default for GUI based browsers, so that their stdout/stderr don't pollute the main program's output. This can be overridden by `webbrowser::open_browser_with_options`.
