To install Viper, do:

		uncompress viper.tar.Z
		tar xf viper.tar


Then do the following:

1. To compile Lisp:
		
      	    	make elc
   
   Since the DVI and Info files are bundled with the distribution, this is
   the only make command you need.
   
2. To recompile the DVI files (if you have to), type:
		
	       make dvi
		
3. To re-make the info files (if needed), type:

	       make info
	       
4. To redo everything:

	       make all
	       
   "make all" is useful if you made your own changes to the *.texi or
   *.el files. This way, this single command will recompile exactly what's
   needed.
   
5. You can also run

	       make install
	       
   to do what "make all" does plus to copy viper*.elc into
   a suitable Lisp directory and Viper Info files into the Info
   directory; DVI files containing printable version of Viper
   Manual and Reference Card will be copied into the 'etc' directory.
   
   You will still have to edit the 'dir' file manually (see below), if
   you haven't done so during a previous installation.
   
   To make all this happen, you will most likely have to change the PREFIX
   variable in Makefile and, possibly, one or more of these variables:
   
   	DATADIR, LISPDIR, INFODIR, ETCDIR, and VERSION
	
   if they don't point to the right directories in your installation.
   You also need to have a write permission for all directories
   mentioned in LISPDIR, INFODIR, and ETCDIR.
   
6. XEmacs users must invoke make with the parameter EMACS=xemacs
   or whatever name is used to invoke XEmacs (some sites still use xemacs
   for Emacs 18). An even better thing would be to edit Makefile directly
   as indicated in the comments there.

For manual installation, copy viper.elc into a directory on your load-path.

To install on-line documentation, you need to install the Info files
by copying the files

viper.info*

into your Info directory (which is emacs-root-dir/info,
if emacs-root-dir is the root directory of the installation).

Then edit the file 

emacs-root-dir/info/dir

to include the root menu item for Viper (check how other menu
items look like in this file).

In Emacs, this item should look like this:

* Viper: (viper.info).    A VI Plan to Rescue Emacs and a venomous VI PERil

In XEmacs, it should look like:

* Viper::	A VI Plan to Rescue Emacs and a venomous VI PERil


If you need a hard copy of the documentation, the files

viper.dvi
viperCard.dvi

contain the Viper manual and the quick reference card, respectively.
