Generates JavaScript and optionally alternative content for SWFObject v2.0:
http://code.google.com/p/swfobject/wiki/documentation

Pass a block with alternative content to also create a div containing it:

  <% swf_object(...) do %>
    <p>Get Flash, fool!</p>
  <% end %>

Like other helpers that take blocks, this will concatenate the generated code to
the ERB output stream directly, so use <% %> instead of <%= %> if a block is given.

Or, pass :alt => true to generate string output including default alternative content:

  <%= swf_object(..., :id => 'alt_content', :alt => true) %>
  # => <div id='alt_content'>This website requires ...</div><script ...

or pass :alt => "some string" to put that in the alternative content:
  <%= swf_object(..., :id => 'alt_content', :alt => "no flash") %>
  # => <div id='alt_content'>no flash</div><script ...

By default, or if you explicitly pass :alt => false, you will have to create the
alternative content element yourself.
