   #
-  #   <%= render :partial => "contract" %>
+  #   <%= render :partial => "account", :object => @buyer %>
   #
-  # within contract we'll get <tt>@contract</tt> in the local variable +contract+, as if we had written

-  #   <%= render :partial => "contract", :locals => { :contract  => @contract } %>
+  #   <%= render :partial => "account", :locals => { :account => @buyer } %>

-  #
-  #   <%= render :partial => "contract", :as => 'agreement' %>
