Licensing

The reason that the program is separated from the modules is that the application will have the GPL license, but the modules can have any other license. This is important because the program will be freely available, but the modules will not come with the program. This allows the authors of the modules to charge for them if they wish. For example, instead of making money on text books, an author can make money by creating worthy problems. Economically, the best problems will gain the greatest monetary returns. The problem sets will be chosen by the professors and assigned to their students, so educators will be responsible for financing those most worthy. The general information available on each topic should be freely available (since knowledge should be in the free domain). It will be important that ALL material be properly sited and not in the sense that it is sited from a text book, but instead from the person or company that developed the theories or made the discovery.
