License Terms

`We' refers to the copyright holders. `You' refers to the licensee. `Renew' refers to the complete set of sources, executables, and sample nets that make up the Reference Net Workshop.

Renew is available free of charge, but not without restrictions. The majority of Renew is published under the GNU Lesser General Public License (for details see Section Original Parts below). However, Renew builds up on other people's work that has been licensed under other terms.

The license section got a bit long. We apologize, but we cannot hope to do better, because we included many external parts with many different licenses.

Contributed Parts

The Collections Package

The collections package is used as our set/queue/list implementation. The relevant license information states:

Originally written by Doug Lea and released into the public domain.

You can use it as you want. Please note that Doug Lea now suggests to use the container libraries that come with Java 1.2 instead of his own libraries. We are currently working on the migration, so far all plug-ins except the FS plug-in have been adopted to the Java container classes.

The JHotDraw Package

The JHotDraw graphical editor written by Erich Gamma is copyrighted. The relevant license information states:

JHotDraw is copyright 1996, 1997 by IFA Informatik and Erich Gamma.

It is hereby granted that this software can be used, copied, modified, and distributed without fee provided that this copyright notice appears in all copies.

Code Generated from JavaCC

Some of the code of Renew was generated by the parser generator JavaCC. The relevant license information states:

3. DEVELOPED PRODUCTS

You may use the Software to generate software program(s) ("Developed Programs"). Sun claims no rights in or to the Developed Programs.

4. YOUR INDEMNIFICATION OF SAMPLE GRAMMARS DERIVATIVES AND DEVELOPED PRODUCTS

You agree to indemnify, hold harmless, and defend Sun from and against any claims or suits, including attorneys' fees, which arise or result from any use or distribution of Sample Grammar Derivatives and/or Developed Programs.

Hence we would like to explicitly point out that Sun is not responsible for any problems that might result from the use of the output of JavaCC.

Bill's Java Grammar

A Java grammar billsJava1.0.2.jj was distributed together with JavaCC 0.7 as a sample grammar. Bill McKeeman (mckeeman@mathworks.com) contributed this grammar to JavaCC. The relevant license information from Sun states:

2. SAMPLE GRAMMARS

You may modify the sample grammars included in the Software to develop derivatives thereof ("Sample Grammar Derivatives"), and sublicense the Sample Grammar Derivatives directly or indirectly to your customers.

4. YOUR INDEMNIFICATION OF SAMPLE GRAMMARS DERIVATIVES AND DEVELOPED PRODUCTS

You agree to indemnify, hold harmless, and defend Sun from and against any claims or suits, including attorneys' fees, which arise or result from any use or distribution of Sample Grammar Derivatives and/or Developed Programs.

The original parts of billsJava1.0.2.jj which are now contained in a modified form in the files JavaNetParser.jj, FSNetParser.jj, FSParser.jj, and StubParser.jj are Copyright (C) 1996, 1997 Sun Microsystems Inc. A sublicense for these grammars is hereby granted. If you have any further questions, please consult the file COPYRIGHT as distributed with JavaCC.

Graph Layout Algorithm

The graph layout algorithm used in the class de.renew.util.GraphLayout was originally provided by Sun as part of the Java Development Kit. The relevant license information from Sun states:

Sun grants you ("Licensee") a non-exclusive, royalty free, license to use, modify and redistribute this software in source and binary code form, provided that i) this copyright notice and license appear on all copies of the software; and ii) Licensee does not utilize the software in a manner which is disparaging to Sun.

This software is not designed or intended for use in on-line control of aircraft, air traffic, aircraft navigation or aircraft communications; or in the design, construction, operation or maintenance of any nuclear facility. Licensee represents and warrants that it will not use or redistribute the Software for such purposes.

We would like to explicitly point out that Sun is not responsible for any problems that might result from the use of the graph layout algorithm. See the source files for Sun's original disclaimer.

The FreeHEP VectorGraphics package

Renew comes with an unmodified version of Java libraries provided by the the FreeHEP project to support several export formats like EPS, PDF, SVG or PNG. The FreeHEP libraries are provided under the same license as Renew itself (the Gnu Lesser General Public License, for a link see below) which allows the unmodified inclusion of a binary distribution within other projects.

Original Parts

This copyright section deals with those part of Renew that are not based on other works, i.e. the example nets and the packages fs and de.renew without the JavaCC grammars.

Example Nets

The example nets are in the public domain. You may modify them as you like. You may use them as the basis for your own nets without restrictions.

Java Source Code and Executables

Sources and executables are copyright 1998--2009 by Olaf Kummer, Frank Wienberg, Michael Duvigenau, Lawrence Cabac, and others. You can distribute these files under the GNU Lesser General Public License.

You will receive a copy of the GNU Lesser General Public License along with Renew in the file doc/COPYING.

Created Parts

You are permitted to use works that you create with Renew (i.e., Java stubs, net drawings, PostScript output, simulation states, and other exported data) without restrictions.

Disclaimer

We distribute Renew in the hope that it will be useful, but without any warranty; without even the implied warranty of merchantability or fitness for a particular purpose.

We are not liable for any direct, indirect, incidental or consequential damage including, but not limited to, loss of data, loss of profits, or system failure, which arises out of use or inability to use Renew or works created with Renew. This clause does not apply to gross negligence or premeditation.

Some parts of Renew may use patented techniques that may not be freely usable in some countries. In that case, it is the responsibility of the user of Renew to obtain a license on the aforementioned techniques before using Renew.

Some parts of Renew may include additional disclaimers in their license terms. In such cases, both disclaimers hold simultaneously. If one clause of any disclaimer is found invalid under applicable law, this does not affect the validity of the remaining clauses or of other disclaimers.

The applicable court is Hamburg, Germany.
