% Redefine \Height to include header and footer space.
\Height=\dimexpr(\Height + 8\lineheight)
% Set up the page layout using the calculated parameters.\setuplayout[ backspace=\the\Back, height=\the\Height, width=\the\Width, header=2\lineheight, headerdistance=\lineheight, footer=2\lineheight, footerdistance=3\lineheight, topspace=\Top]

</texcode>
This can be processed with a <code>-mode=BCOR</code> option on <code>texexec</code> to activate the binding correction, or with a <code>-mode=oneside</code> option to activate the single-sided page layout rather than the (default) double-sided version.
