README

This program has been developed on Unix systems, but runs
on windows systems, too.

Installation under Unix

1. check
--------
Your operating system should be Linux (versions from 2.0.35),
SunOS (versions from 5.6), or OSF1(V4.0).

We assume Tcl/Tk software with a version 8 or higher
is installed separately. If you miss information, try
http://www.scriptics.com/software/

The VITESS software comes to you as a gzipped tar file.
When your browser asks for a file name to store the tar file,
it might suggest
	vitess_download
without any .tar.gz extension. We assume you change that default
to a name with .tar.gz ending like vitess.tar.gz .

You may compare the CRC32 or MD5 checksums of the downloaded
vitess.tar.gz with those stated at
https://www.hmi.de/projects/ess/vitess/checksums.txt

The file vitess.tar.gz might be de-tared in whatever
<vitess parent directory> you want, like /usr/bin for root installation
or $HOME for personal installation.

2. do
-----
	cd <vitess parent directory>
	gtar -zxvf vitess.tar.gz

	(if you do not have gtar, try
		gunzip vitess.tar.gz
		tar -xvf vitess.tar
	)	

3. edit script
--------------
Please change the first line of the vitess start script
	<vitess parent directory>/vitess/Vitess
from
	#!/usr/local/bin/bltwish
to the correct path of the bltwish image.
If you do not have a bltwish installed, just take the normal wish.
We used vitess with different versions of wish and bltwish, but
recommend the latest versions 8.4 / 2.4.

(Due to a bug in /usr/local/lib/tk8.4/tkfbox.tcl browsing
directories and files fails. We send you a patch on request.)

4. try it
---------
	<vitess parent directory>/vitess/Vitess
