+%    \subsection{The \pkg{topcapt} package and the \pkg{subfig} package}
+%    nagdemo exhibits an error when topcapt and subfig are used
+%    together, i.e. \pkg{subfig} thinks the caption has not been
+%    stepped already. This is not a bug in \pkg{nag}.
+%
+%    \subsection{The \pkg{rotating} package}
+%    \pkg{rotating} uses \cmd{\centerline} to place rotated floats. As
+%    far as I can see, the usage is legitimate there, and using
+%    \cmd{\centering} instead would change behaviour when the float's
+%    dimension are larger than the text body. (Currently, the height
