Viper
*****

   We believe that one or more of the following statements are adequate
descriptions:

     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 GNU Emacs
19 and XEmacs 19. Because of its reliance on minor mode keymaps, Viper
will not work under Emacs 18. Viper implements most Vi and Ex commands.
It gives you the best of both worlds: Vi keystrokes for editing
combined with the GNU Emacs environment. Viper also fixes some common
complaints with Vi commands.  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.  Viper tries to be compatible with these 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 would be 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.emacs.edu' is the
current address for Viper bug reports.  Please use the Ex command
`:submitReport' for this purpose.
