This action will serialize the body of an HTTP Response. The serializer is
selected by introspecting the HTTP Requests content-type header.
-It requires that your Catalyst controller have a "serialize" entry
-in it's configuration, which sets up the mapping between Content Type's
-and Serialization classes.
+It requires that your Catalyst controller is properly configured to set up the

-The specifics of serializing each content-type is implemented as
-a plugin to L<Catalyst::Action::Serialize>.

Typically, you would use this ActionClass on your C<end> method. However,
nothing is stopping you from choosing specific methods to Serialize:

+When you use this module, the request class will be changed to

-Takes a hashref, mapping Content-Types to a given plugin.
+Specifies the key of the stash entry that optionally holds an overriding

+This can be useful if you want to dynamically force a particular content type,
+perhaps for debugging.

Daisuke Maki pointed out that early versions of this Action did not play
well with others, or generally behave in a way that was very consistent
