I'm not too familiar with the tutorial, or TTSite, but the standard
Catalyst var entry is simply "c" for just Catalyst::View::TT on its
own.  Some other folks use "ctx", but I think "c" is the standard
default.

You can set it to any value that you like, but it is something to be
mindful of if you bounce between other apps, or apps that others have
written (like the plethora of examples in svn).
