+dogtail-detect session
+
+This script checks for some main pieces of a running GNOME session, 
+specifically gnome-panel and metacity. 
+
+It checks to see that the gnome-panel node has at least some child nodes.
+For example, the main gnome-panel node by default has two direct descendents:
+the top panel, and the bottom panel.
+Metacity's existence is also checked. However, metacity currently never has
+any child nodes.
+
+If a proper session is running, the scripts exits with a status of 0.
+If no session is found, a non-zero exit code is returned.
