This macro is not for the faint at heart. It can be used throughout all skins of your site and renders the skin referred to with the name parameter, e.g.

<% site.skin name="frontpage" %>
<% poll.skin name="graph" %>

For example, the story skins "preview" and "full story" use this macro to embed the "display" skin:

<% story.skin name="display" %>

Please be aware that the embedded skin must be available from within the skin you are entering the macro. E.g. you cannot call the "poll results" skin from within a file skin (and vice versa).

Furthermore, this macro might only make sense in certain places. So think very well before you randomly add this macro somewhere.
