Clean license conditions

Clean and its standard libraries are available under two different licenses:

• The LGPL, the standard GNU Lesser General Open Source license, which is free of charge
• A commercial license that can be obtained from Prof.dr.ir. M.J. Plasmeijer, preferably via email: rinus@cs.ru.nl

Note, that development under the LGPL license entails some restrictions and responsibilities. More information on the nature of the LGPL is available at http://www.gnu.org/ and http://www.opensource.org .

A commercial license has the advantage that one is not obligated to make source code available. It furthermore gives right to technical support and is highly appreciated as a sign that you appreciate our work.

Users can choose under which license they wish to operate under.
