+### Javascript
+
+Some plugins use javascript to make ikiwiki look a bit more web-2.0-ish.
+
+All javascript code should be put in `.js` files in the `javascript`

+calling `add_underlay("javascript");` in their `import` function.

+You'll have to arrange for `<script>` tags to be added to the pages that
