This software uses some non-free libraries for which exceptions appear in thesource code license inserts. It is suggested that anyone who thinks of doingsubstantial further work on this program should first free it from dependenceon the non-free libraries so that it does the same job without the non-freelibraries. Further introduction of non-free libraries likely would require arevised license and thus permission from all contributors to the codebase.That being problematic, any additional non-free libraries are unlikely to beaccepted by Cyan Worlds or the development community.
