+ <h2 id="modularization-example">Modularization Example</h2>
+<p>The following diagram shows how the image capture sequence
+differs if different provisioning modules are used -- xCAT and
+VMWare.</p>
+<p>Take note of the following:</p>
+<ul>
+<li>The calls made by image.pm to the xCAT and VMWare capture()
+subroutines are <strong>identical</strong>. The image.pm state module does not
+care which provisioning engine is being used. All it knows is that a
+provisioning engine object has been created before image.pm::process() was
+called, the object can be accessed via $self->provisioner, and the
+name of the subroutine to call is capture().</li>
+<li>The calls made by xCAT and VMWare's capture() subroutine to the
+Windows.pm pre_capture() subroutine are <strong>identical</strong>. All a
+provisioning engine module needs to know is that an OS object has been
+created, the object can be accessed via $self->os, and the name of the
+subroutine to call is pre_capture().</li>
+<li>Provisioning engine modules do not not need to know any of the operating
+system details. They assume the OS module's pre_capture()
+subroutine will perform all the steps necessary for the particular OS to be
+captured and that the computer will be shut down (or left in the state
+specified by the end_state argument) when pre_capture() returns.</li>
+<li>The OS module's pre_capture() subroutine does not care which
+provisioning engine is being used. The steps it performs are
+identical.</li>
+<li>A very similar example could be made using the same provisioning engine
+module and different OS modules.</li>
+</ul>
