I asked Anders about the license off list before William's post. To clarify this, he changed the LICENSE file to the following : -------------- The Gfan software is distributed under the "GNU GENERAL PUBLIC LICENSE" version 2 or any later version as described in the file "COPYING". Ask the author if you want a more reasonable license. -------------- This will be in a later release of gfan.
