(description
"Readline is a libary that allows users to edit command lines as they
are typed in. It can maintain a searchable history of previously entered
commands, letting you easily recall, edit and re-enter past commands. It
features both Emacs-like and vi-like keybindings, making its usage
comfortable for anyone.")
