<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
