 Viper
 *****
 
 We believe that one or more of the following statements are adequate
 descriptions of Viper:
 
      Viper Is a Package for Emacs Rebels;
      it is a VI Plan for Emacs Rescue
      and/or a venomous VI PERil.
 
    Technically speaking, Viper is a Vi emulation package for Emacs.  It
 implements all Vi and Ex commands, occasionally improving on them and
 adding many new features.  It gives the user the best of both worlds: Vi
 keystrokes for editing combined with the power of the Emacs environment.
 
    Viper emulates Vi at several levels, from the one that closely
 follows Vi conventions to the one that departs from many of them.  It
 has many customizable options, which can be used to tailor Viper to the
 work habits of various users.  This manual describes Viper,
 concentrating on the differences from Vi and new features of Viper.
 
    Viper, formerly known as VIP-19, was written by Michael Kifer.  It is
 based on VIP version 3.5 by Masahiko Sato and VIP version 4.4 by Aamod
 Sane.  About 15% of the code still comes from those older packages.
 
    Viper is intended to be usable without reading this manual; the
 defaults are set to make Viper as close to Vi as possible.  At startup,
 Viper will try to set the most appropriate default environment for you,
 based on your familiarity with Emacs.  It will also tell you the basic
 GNU Emacs window management commands to help you start immediately.
 
    Although this manual explains how to customize Viper, some basic
 familiarity with Emacs Lisp is a plus.
 
    It is recommended that you read the Overview node.  The other nodes
 may be visited as needed.
 
    Comments and bug reports are welcome.  ‘kifer@cs.stonybrook.edu’ is
 the current address for Viper bug reports.  Please use the Ex command
 ‘:submitReport’ for this purpose.
