== Example ==
The following example defines a create_wave macro that is then used for the page background.
<texcode>
\startMPinclusions
\stopMPinclusions
\startuseMPgraphic{page:ThemeBackground}
path wave;
wave := create_wave;
draw wave xyscaled( 60, 20 ) withpen pencircle scaled 1mm;
\stopuseMPgraphic
\defineoverlay[page:ThemeBackground][\uniqueMPgraphic{page:ThemeBackground}]
\starttext
\setupbackgrounds[page][background={page:ThemeBackground}]
\startchapter
\input knuth
\input zapf
\input knuth
\stopchapter
\stoptext
</texcode>
== Multiple Inclusions ==
To use multiple {{cmd|startMPinclusions}} that should be combined, use ''[+]''. For example, the following code will fail because the second inclusion overwrites the first:
<pre>
\startMPinclusions
path a ;
\stopMPinclusions
\startMPinclusions
a := (0,0) -- (1cm,0) ;
\stopMPinclusions
</pre>
Use ''[+]'' to appended the second inclusion after the first:
<pre>
\startMPinclusions
path a ;
\stopMPinclusions
\startMPinclusions[+]
a := (0,0) -- (1cm,0) ;
\stopMPinclusions
</pre>
