+Stylesheets and Javascripts can be added to every layout and sub-layout at
+runtime with L<SL::Layout::Dispatcher/add_stylesheets> and
+L<SL::Layout::Dispatcher/add_javascripts> (C<use_stylesheets> and
+C<use_javascripts> are aliases for backwards compatibility):
+
+ $layout->add_stylesheets("custom.css");
+ $layout->add_javascripts("app.js", "widget.js");
+
+Or they can be overwritten in sub layouts with the calls
+L<SL::Layout::Displatcher/static_stylesheets> and
+L<SL::Layout::Dispatcher/static_javascripts>:
+
+ sub static_stylesheets {
+ "custom.css"
