+rlwrap is a 'readline wrapper' that uses the GNU readline library
+to allow the editing of keyboard input for any other command. Input
+history is remembered across invocations, separately for each command;
+history completion and search work as in bash and completion word
+lists can be specified on the command line.
+
+You will need to create the ~/.rlwrap directory (or wherever RLWRAP_HOME is
+set to) or rlwrap will complain and exit.
