+\subsection{Specifying viewport in the \pkg{graphics} package}
+Specifying a BoundingBox does not really have meaning when including non-EPS graphics in
+\pdfTeX\ and \LuaTeX. For some years the \pkg{graphicx} package
+\texttt{bb} key has been interpreted (with a warning) as a
+\texttt{viewport} key. This feature has been added to the two-argument
+form of \verb|\includegraphics| which is mostly used in the
+\pkg{graphics} package. \verb|\includegraphics[1,2][3,4]{file}| will
+be interpreted in \pdfTeX\ and \LuaTeX\ in the same way as \pkg{graphicx}
+\verb|\includegraphics[viewport=1 2 3 4]{file}|.
+
+\subsection{Normalizing \cs{endlinechar}}
+If \cs{endlinechar} is set to $-1$ so that ends of lines are ignored
+in special contexts, then a low level \TeX\ error would be generated
+by code parsing BoundingBox comments. The package now locally sets
+\cs{endlinechar} to its standard value while reading files.
