<title>Customizing the Generic Builder</title>
<para>The operation of the generic builder can be modified in many
places by setting certain variables. These <emphasis>hook
variables</emphasis> are typically set to the name of some shell
function defined by you. For instance, to perform some additional
steps after <command>make install</command> you would set the
<varname>postInstall</varname> variable:
<programlisting>
postInstall=myPostInstall
myPostInstall() {
mkdir $out/share/extra
cp extrafiles/* $out/share/extra
}</programlisting>
</para>
