GNU `nano' is a small and friendly text editor. Besides basic text
editing, `nano' offers many extra features like an interactive search
and replace, goto line number, auto-indentation, feature toggles,
internationalization support, and filename tab completion.
The original goal for `nano' was a complete bug-for-bug compatible
emulation of Pico, but consistency is now a slightly higher priority.
Nano does not have the restrictive license problems of Pico.
