27You can insert arbitrary code in the generated cpps, just use the functions
28<tt>declaration_code</tt> and <tt>module_code</tt>. This will insert the given string in the
29respective sections. Example:</p>
30<code><pre>
31    ##<span class=identifier>file </span><span class=identifier>A</span><span class=special>.</span><span class=identifier>pyste
32    </span><span class=identifier>Class</span><span class=special>(</span><span class=string>&quot;A&quot;</span><span class=special>, </span><span class=string>&quot;A.h&quot;</span><span class=special>)
33    </span><span class=identifier>declaration_code</span><span class=special>(</span><span class=string>&quot;/* declaration_code() comes here */\n&quot;</span><span class=special>)
34    </span><span class=identifier>module_code</span><span class=special>(</span><span class=string>&quot;/* module_code() comes here */\n&quot;</span><span class=special>)
35</span></pre></code>
