Specialising slot-based Layouts

layout/products:

%%  into layout/main
%%      block header
            This is a new header for this section.
            It's a block so you can't re-define it.
%%      end

%%      slot content
            This is some new default content for this section.  
            It's a slot so you can over-ride it.
%%      end
%%  end 
--EOF--

Thus Spake Andy:

We can "subclass" our master layout to create a slightly different layout. For example, we might want to define a different header for all the product pages in a web site. If we define the header as a block then it fixes the new header in place. A block blocks any further replacement (similar to the final keyword in Java which prevents a method from being re-defined by subclasses). In contrast, we define the content as a slot so that other templates can continue to slot in an alternative.
