+The rename plugin can add a "rename" hook, which other plugins can use to
+update links &etc. The hook would be passed page content, the old and new
+link names, and would modify the content and return it. At least the link
+plugin should have such a hook.
+
+After calling the "rename" hook, and rendering the wiki, the rename plugin
+can check to see what links remain pointing to the old page. There could
+still be some, for example, CamelCase links probably won't be changed; img
+plugins and others contain logical links to the file, etc. The user can be
+presented with a list of all the pages that still have links to the old
+page, and can manually deal with them.
