  68        "The GNU Readline library provides a set of functions for use by
  69 applications that allow users to edit command lines as they are typed in.
  70 Both Emacs and vi editing modes are available.  The Readline library includes
  71 additional functions to maintain a list of previously-entered command lines,
  72 to recall and perhaps reedit those lines, and perform csh-like history
  73 expansion on previous commands.
  74
  75 The history facilites are also placed into a separate library, the History
  76 library, as part of the build process.  The History library may be used
  77 without Readline in applications which desire its capabilities.")
