- No.
-
- You will still need to obtain a profesional version of
- deal.II from the authors to make commercial
- (proprietary) software with deal.II
- (unless, as always, you release software as free/Open Source
- software).
-
- Yes.
-
- You may copy and redistribute deal.II, both
- at home and at work, without restrictions.
- The QPL prohibits development of
-proprietary software. For Qt our Qt Professional
-Edition product is available for this.
+
+ deal.II is placed under an Open Source license,
+ in the sense advocated by the
+ Open Source
+ Initiative. You are thus free to copy and use it, and you have
+ free access to all source codes.
+
+ The license under which we have placed deal.II is
+ called the Q Public License (or "QPL"), and qualifies as an Open Source
+ license. It is thus appropriate for people wishing to write
+ software under the Open Source model where all source code to the
+ software is made available to all users and can be freely modified
+ and redistributed. The QPL was originally developed by
+ Troll Tech for their
+ Qt program library, but has since gained some support by other
+ library authors as well.

+ The QPL prohibits development of proprietary software. If you intend
+ to develop commercial software based on deal.II,
+ we are willing to negotiate a different agreement. Feel free to
+ contact us in this case.
+ For more information on the QPL, please see also the following
+ links:
+
+ In addition to the terms imposed by the QPL, we have one restriction
+ on the use of the library:

+ Please note that by this we do not mean to restrict your freedom of

+ the development of the library in regular reviews which our
+ institute has to undergo.
