+Note that we could have used something like C<sub default :Private>; 
+however, the use of C<default> actions is discouraged because it does
+not receive path args as with other actions.  The recommended practice 
+is to only use C<default> in C<MyApp::Controller::Root>.
+
+Another options would be to use something like 
+C<sub base :Path :Args(0) {...}> (where the C<...> refers to the login 
+code shown in C<sub index : Private> above). We are using C<sub base 
+:Path :Args(0) {...}> here to specifically match the URL C</login>. 
+C<Path> actions (aka, "literal actions") create URI matches relative to 
+the namespace of the controller where they are defined.  Although 
+C<Path> supports arguments that allow relative and absolute paths to be 
+defined, here we use an empty C<Path> definition to match on just the 
+name of the controller itself.  The method name, C<base>, is arbitrary. 
+We make the match even more specific with the C<:Args(0)> action 
+modifier -- this forces the match on I<only> C</login>, not
