"The GNU readline library 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.")

(description
"Rlwrap is a 'readline wrapper', a small utility that uses the GNU
readline library to allow the editing of keyboard input for any command. You
should consider rlwrap especially when you need user-defined completion (by way
of completion word lists) and persistent history, or if you want to program
'special effects' using the filter mechanism.")
