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.
