| /** |
| * |
| * This class implements a Text_Wiki_Parse to find source text marked as a |
| * wiki freelink, and automatically create a link to that page. |
| * |
| * A freelink is any page name not conforming to the standard |
| * StudlyCapsStyle for a wiki page name. For example, a page normally |
| * named MyHomePage can be renamed and referred to as ((My Home Page)) -- |
| * note the spaces in the page name. You can also make a "nice-looking" |
| * link without renaming the target page; e.g., ((MyHomePage|My Home |
| * Page)). Finally, you can use named anchors on the target page: |
| * ((MyHomePage|My Home Page#Section1)). |
