Internal Program Version: 9.1

nano is a small and friendly editor. It copies the look and
feel of Pico, but is free software, and implements several
features that Pico lacks, such as: opening multiple files,
scrolling per line, undo/redo, syntax coloring, line
numbering, and soft-wrapping overlong lines.

Note:
This package contains manual pages for nano.
