SceneLib License

SceneLib is released with full source code under the GNU Lesser Public License (LGPL), a `copyleft' license which means that anyone is free to use and modify the source code but that modified versions must also be made publically available under the same terms. The LGPL differs from the standard GNU GPL in that it permits unmodified versions of SceneLib to be `linked' with proprietry software without the need to disclose the source code of the proprietry part.
