Signed-off-by: Francois Perrad <francois.perrad@gadz.org>
[Thomas:
 - fix the license information, it's GPLv3+, LGPLv3+.
 - add a comment about the COPYING file containing only the LGPLv3 text,
   even though there is some GPLv3+ code.
 - minor tweaks in the .mk file
 - rewrap Config.in help text.]
