<para>This parameter is useful when printing a document
on both sides of the paper.</para>

<para>if set to non-zero, documents are formatted using different page-masters
for odd and even pages.  These can differ by using a slightly wider margin
on the binding edge of the page, and alternating left-right
positions of header or footer elements.
</para>

<para>If set to zero (the default), then only the 'odd' page masters
are used for both even and odd numbered pages.</para>

<para>See also <parameter>force.blank.pages</parameter>,
<parameter>page.margin.inner</parameter> and
<parameter>page.margin.outer</parameter>.</para>
