Dear all, version 3 of the GNU General Public License (GPLv3), has been released: http://www.fsf.org/news/gplv3_launched I plan to use the copyright holder privileges to change the license of the CVS HEAD version (and thus of any future release) of the Parma University's Recurrence Relation Solver to GPLv3. If you have concerns about this licensing change, please get in touch with me. All the best, Roberto -- Prof. Roberto Bagnara Computer Science Group Department of Mathematics, University of Parma, Italy http://www.cs.unipr.it/~bagnara/ mailto:bagnara@cs.unipr.it
