Nano - Emulate Pico while also offering a few enhancements.

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 nano's main goal is to be as compatible as possible while offering a superset of Pico's functionality.
