&reftitle.required; To use the readline functions, you need to install libreadline. You can find libreadline on the home page of the GNU Readline project, at &url.readline;. It's maintained by Chet Ramey, who's also the author of Bash. You can also use these functions with the libedit library, a non-GPL replacement for the readline library. The libedit library is BSD licensed and available for download from &url.libedit;.
