| /** |
| * This Layout module allows Velocity templates to be used as layouts. |
| * Since dynamic content is supposed to be primarily located in |
| * screens and navigations there should be relatively few reasons to |
| * subclass this Layout. |
| * |
| * To get the same functionality as with VelocityECSLayout, you can use two |
| * supplied VelocityMacros, TurbineHtmlHead and TurbineHtmlBodyAttributes |
| * in your templates. These are used to put HtmlPageAttributes into a page |
| * before rendering. |
| * |
| * Use these macros should be used in the Layout template like this: |
| * |
| * ... set things like style sheets, scripts here. |
| * &lt;html&gt; |
| * #TurbineHtmlHead() |
| * &lt;body #TurbineHtmlBodyAttributes() &gt; |
| * .... your body information |
| * &lt;/body&gt; |
| * &lt;/html&gt; |
| * |
| * As the layout template is rendered _after_ the screen template, you |
| * can of course, add information to the $page tool in your screen template. |
| * This will be added correctly to the &lt;head&gt;...&lt;/head&gt; and |
| * &lt;body&gt; tags. |
