-      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 facilities 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.
