+#
+#  This script is used to mount the filesystem having the
+#  UUID specified in parameter 1 at a fixed path. The path
+#  will be a subdirectory of the path given by the MOUNT_DIR
+#  environment variable, where the UUID is used as the
+#  subdirectory name. The MOUNT_DIR variable is sourced from
+#  /etc/default/vchanger or /etc/sysconfig/vchanger. Also,
+#  the MOUNT_OPTIONS variable may be set to specify additional
+#  options to pass through to the mount command.
+#
+#  Generally, this script is designed to be invoked by a
+#  launcher script, vchanger-launch-mount.sh, that is itself
+#  launched directly by udev in response to a hotplug event.
+#  This is useful for headless systems that do not have an
+#  automount capability such as Gnome Nautilus, but have
+#  non-root daemons that require plug-n-play attachment of
+#  external disk drives.
