--- Comment #2 from Jens Lody fedora@jenslody.de --- Besides this:
%clean can normally be removed, rm -rf %buildroot is deprecated, %defattr(-, root, root) also.
%{_datadir}/licenses/%{name} is unneeded as far as I know.
The descriptions just repeats the summary, is it possible to be more elaborately.
