+% \subsection{Rerun warning}
+%
+% The following code computes a MD5 sum and the file size of the
+% |.brf| file at the begin and the end of the document and compares
+% them. A rerun warning is given, if they do not match.
+% This method requires pdf\TeX\ or Lua\TeX. The method fails,
+% if the MD5 sum and the file size are the same for
+% a changed |.brf| file (it's probably very seldom).
