[Catalyst] How do I have Catalyst access a Controller based on only part of the PATH_INFO

[Steve H]

Hi

I'm used to (albeit a recent Catalyst convert) creating a Controller based 
on the whole name of the PATH_INFO, e.g.
  http://localhost:3000/some/structure/like/this
being:
  package my_app::Controller::some::structure::like::this
In a file my_app/lib/my_app/Controller/some/structure/like/this.pm
How would I have a Controller like:
  package my_app::Controller::some::structure
In a file my_app/lib/my_app/Controller/some/structure.pm
and be able to access the remaining "like/this" via PATH_INFO.

In case you are wondering why... I was wanting to have a catalogue menu hit 
back into the app at a common point, and use the remaining PATH_INFO to 
indicate the specifics of selection made.

This seems like it'd be pretty ordinary to be able to do... just that I 
can't see how to from the Catalyst documentation.  It's probably a case of 
me not being able to see the wood for the trees ... or it being something 
obvious yet documented in an implicit way.... dunno....
going nuts
