+package.  The package offers mechanisms to put floats side by side, and to put
+the caption beside its float.  The @code{floatrow} settings could be expanded
+to the floats created by packages @code{rotating}, @code{wrapfig},
+@code{subfig} (in the case of rows of subfloats), and @code{longtable}.")
