Use this template to create a popup window that is displayed when the mouse is over part of the page. This template has two parameters:

• `mouseover` - This is the text or other content that triggers the popup.
• `popup` - This should be the content of the popup window. It can be anything, even images or a whole little wiki page, but should not be too large for good usability.

Note that browsers that do not support the CSS will display the popup inline in the page, inside parens. []
