+/**
+* HTML_TreeMenu Class
+*
+* A simple couple of PHP classes and some not so simple
+* Jabbascript which produces a tree menu. In IE this menu
+* is dynamic, with branches being collapsable. In IE5+ the
+* status of the collapsed/open branches persists across page
+* refreshes.In any other browser the tree is static. Code is
+* based on work of Harald Radi.
+*
+* Usage.
+*
+* After installing the package, copy the example php script to
+* your servers document root. Also place the TreeMenu.js and the
+* images folder in the same place. Running the script should
+* then produce the tree.
+*
+* Thanks go to Chip Chapin (http://www.chipchapin.com) for many
+* excellent ideas and improvements.
