+      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.
