1. Introduction
===============

This is the 3.6 Alpha 4 release of UPPAAL 3.6 -- a model checker
for timed automata.

Note that UPPAAL is free for non-profit applications but we want all
users to fill in a license agreement. This can be done online on the
web site http://www.uppaal.com/ or by sending in the form attached
below.

This product includes the libxml2 library which is copyrighted as
follows: "Copyright (C) 1998-2005 Daniel Veillard.  All Rights
Reserved."

2. Installation
===============

To install, unzip the zip-file. This should create the directory
uppaal-3.6-alpha4 containing at least the files uppaal,
uppaal2k.jar, and the directories lib, man, bin-Linux, bin-Win32, lib,
man and demo. The bin-directories should all contain the two files
verifyta(.exe) and server(.exe) plus some additional files, depending
on the platform. The demo-directory should contain some demo files
with suffixes .xml and .q.

Note that UPPAAL will not run without Java 2 installed on the host
system. Java 2 for SunOS, Windows95/98/Me/NT/2000/XP, and Linux can be
downloaded from http://java.sun.com.

The present version of UPPAAL does no longer support versions 1.1,
1.2, 1.3 and 1.4 of the Java Runtime Environment (JRE). You need at
least JRE 5, and we strongly recommend using the most recent version
available for your platform.

To run UPPAAL on Linux systems run the script named 'uppaal'. To run
on Windows 95/98/Me/NT/2000/XP systems double click the file
uppaal2k.jar.
