+%description
+The internal patch fuzz value was changed, and could hide patchs issues, or
+could lead to applying a patch at the wrong location. Usually, this is often
+the sign that someone didn't check if a patch is still needed and do not want
+to rediff it. It is usually better to rediff the patch and try to send it

+The use of PreReq is deprecated. In the majority of cases, a plain Requires
+is enough and the right thing to do. Sometimes Requires(pre), Requires(post),
+Requires(preun) and/or Requires(postun) can also be used instead of PreReq.
