+=head2 Delivering a Custom Error Page
 
-When deploying your application it's a waste to serve static files 
-with Catalyst. Instead, set up something like this:
+By default, Catalyst will display its own error page whenever it
+encounters an error in your application. When running under C<-Debug>
+mode, the error page is a useful screen including the error message and
+a full Data::Dumper output of the C<$c> context object. When not in
+C<-Debug>, users see a simple "Please come back later" screen.
 
-    Alias /static/ "/my/static/files/"
-    <Location "/static">
-    SetHandler none
-    </Location>
+To use a custom error page, use a special C<end> method to short-circut
+the error processing. The following is an example; you might want to
+adjust it further depending on the needs of your application (for
+example, any calls to C<fillform> will probably need to go into this
+C<end> method; see L<Catalyst::Plugin::FillInForm>).
