     "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.")
