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.")

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.")
