Sets 'path_prefix', as described below.
+=head2 action_args
+
+Allows you to set instantiation arguments on your custom Actions or ActionRoles.
+You can set args globally (shared across all actions) and specifically (for a
+single action).
+
+ package MyApp::Web::Controller::MyController;
+ use parent 'Catalyst::Controller';
+
+ __PACKAGE__->config({
+ action_args => {
+ '*' => {globalarg1=>'hello', globalarg2=>'goodbye'},
+ 'specific_action' => {customarg=>'arg1'},
+ },
+ });
+
+ sub specific_action :Path('') ActionClass('CustomActionClass') {}
+
+ 1;
+
+In the case above, your 'CustomActionClass' would get passed the following
+arguments when it is instantiated: (globalarg1=>'hello', globalarg2=>'goodbye',
+'customarg=>'arg1'). Please note that the order the arguments are passed are not
+certain to be in the order declared.
+
+As with all other configuration hashes, you can set values inline with your
+controller (as above) or centrally via a configuration file (such as you might
+use with the ConfigLoader plugin).
