# runvdr: Loads the DVB driver and runs VDR
#
# If VDR exits abnormally, the driver will be reloaded
# and VDR restarted.
#
# Set the environment variable VDRUSR to the user id you
# want VDR to run with. If VDRUSR is not set, VDR will run
# as 'root', which is not necessarily advisable.
#
# Since this script loads the DVB driver, it must be started
# as user 'root'.
#
# Any command line parameters will be passed on to the
# actual 'vdr' program.
#
# See the main source file 'vdr.c' for copyright information and
# how to reach the author.
