-This is the Catalyst Request class, which provides a set of accessors to the
-request data. The request object is prepared by the specialized Catalyst
-Engine module thus hiding the details of the particular engine implementation.

+This is the Catalyst Request class, which provides an interface to data for the
+current client request. The request object is prepared by L<Catalyst::Engine>,
+thus hiding the details of the particular engine implementation.
=head1 METHODS
-=over 4
+=head2 $req->action
-=item $req->action
+Returns the requested action as a L<Catalyst::Action> object.
-Contains the requested action.
+=head2 $req->address
- print $c->request->action;
+Returns the IP address of the client.
-=item $req->address
+=head2 $req->arguments
-Contains the remote address.
+Returns a reference to an array containing the arguments.
- print $c->request->address
+ print $c->request->arguments->[0];
-=item $req->args
+For example, if your action was
-Shortcut for arguments
+ package MyApp::C::Foo;
+
+ sub moose : Local {
+ ...
+ }
-=item $req->arguments

+Shortcut for arguments.
+
+=head2 $req->base
+

+=head2 $req->param
-Get request parameters with a CGI.pm like param method.
+Returns GET and POST parameters with a CGI.pm-compatible param method. This

+Like L<CGI>, and B<unlike> earlier versions of Catalyst, passing multiple
+arguments to this method, like this:
+
+ $c->request->param( 'foo', 'bar', 'gorch', 'quxx' );
+
+will set the parameter C<foo> to the multiple values C<bar>, C<gorch> and
+C<quxx>. Previously this would have added C<bar> as another value to C<foo>
+(creating it if it didn't exist before), and C<quxx> as another value for
