DESCRIPTION: The GNU Readline library provides a set of functions that allow app-native CLI editing.

The GNU Readline library provides a set of functions for use by applications
that allow users to edit command lines as they are typed in.  Both Emacs and
vi editing modes are available.  The Readline library includes additional
functions to maintain a list of previously-entered command lines, to recall
and perhaps reedit those lines, and perform csh-like history expansion on
previous commands.

The history facilites are also placed into a separate library, the History
library, as part of the build process.  The History library may be used
without Readline in applications which desire its capabilities.

Readline is free software, distributed under the terms of the GNU General
Public License, version 3.  This means that if you want to use Readline in a
program that you release or distribute to anyone, the program must be free
