----Think of the base class (phphtmllibPage) as the 'template'  It knows 
how to render the layout of the site.  So all each specific page of the site
has to do is override 1 method of the base class to get the content that 
is specific for that page.  It creates a system that helps you focus on 
the functionality
that matters most for each page, instead of worrying about layout issues 
on each page.  You don't care about the layout, you only want to worry 
about what that specific page provides as part of the application.  That 
being said, you can also override other methods of the base 
phphtmllibPage class to provide new left
nav content (different menus).  So all you have to do is provide new 
links in the content that will go to the next script.  index.php doesn't 
care about what foo.php page does, only that it provides a link to it.  
it leaves the content for foo.php up to foo.php.  The base class 
provides the layout framework. 

It's just a different approach to templating, which I believe provides 
more long term flexibility then a static template does, but thats 
irrelevant.
