+through themes and an option file; is suitable for machines on which remote login
+functionalities are not needed.
+
+Features included: PNG and XFT support for alpha transparency and antialiased fonts,
+External themes support, Configurable runtime options: X server -- login / shutdown / reboot
+commands, Single (GDM-like) or double (XDM-like) input control, Can load predefined user at
+startup, Configurable welcome / shutdown messages, Random theme selection")
