+     "Graphbox is an extension of the standard @code{graphicx} LaTeX2e package to
+allow the placement of graphics relative to the ``current position'' using
+additional optional arguments of @code{\\includegraphics}.  For example,
+changing the vertical alignment is convenient for using graphics as elements
+of (mathematical) formulae.  Options for shifting, smashing and hiding the
+graphics may be useful in support, for example, of the Beamer framework.")
