License

Juggling Lab is comprised of software from multiple sources, each with a slightly different license:

• idx3d 3d library used for the 3d rendering mode -- copyright Peter Walser, free for non-commercial use only.
• AElfred XML parser -- copyright Microstar Software Ltd., free for both commercial and non-commercial use.
• Jakarta-Regexp regular expressions package -- copyright The Apache Software Foundation, free under the Apache Software License version 1.1. This product includes software developed by the Apache Software Foundation (http://www.apache.org/).
• Selected portions of HTTPClient used for file uploading -- copyright Ronald Tschalär, free under the GNU Lesser General Public License (LGPL).
• All other Juggling Lab code -- copyright Jack Boyce and others, free under the GNU General Public License (GPL).

The upshot is that Juggling Lab can be freely used and redistributed for non-commercial purposes only. If you have commercial aspirations, you'll need to talk with Peter Walser or figure out a way to remove or replace the 3d library.

Last but important, if you make the code publicly available in any way (e.g., you post it on a web site), then you are required by the GPL to include the corresponding source code in a machine-readable format. The recommended way to do this is to always include the JugglingLab_source.jar file in the same directory as the executable jar files. If you change the source code and rebuild with Apache Ant using the included build file, the JugglingLab_source.jar file will be recreated to incorporate your changes; it is your responsibility to ensure that the source archive corresponds to the executables you make available.
