+command.  For older formats it implements @code{\\AtEndDvi}, a counterpart to
+@code{\\AtBeginDvi}.  The execution of its argument is delayed to the end of
+the document at the end of the last page.  Thus @code{\\special} and
+@code{\\write} remain effective, because they are put into the last page.
+This is the main difference to @code{\\AtEndDocument}.")
