There's no "single template" implied. By default you're probably going to have 
a template per-action, though that's completely up to you, and TT provides 
tools such as WRAPPER, INCLUDE, and BLOCK to let you organize and reuse your 
code. I'd suggest spending a little time with the Template::Manual as well as 
having a look at some real-life Catalyst apps.
