<h1>Multiple Modules</h1>
<div class="exampleIntro">
<p>
This example demonstrates how to use the Browser History Manager
with several different modules. Working with several modules
is not different from working with a single module. All the modules
have to be registered separately, and each module has its own
initial state and callback.
