#
# This script is the gpsd udev handler for add/remove events on matched USB
# devices. It expects to see the following environment variables:
+#
# ACTION = either "add" or "remove"
# DEVNAME = the full name of the USB device that was just activated
+#
+# It will accept from /etc/sysconfig/gpsd the following config variables:
+#
+# CONTROL_SOCKET = location of the gpsd control socket
+# OPTIONS = options to be passed to gpsd on launch
+#
# It hands off to gpsdctl for the actual communication with the daemon.
#
+# Do not introduce bashims into this script, as we want it to continue to
+# work under Ubuntu.
