# runvdr: Loads the DVB driver and runs VDR
#
# If VDR exits abnormally, the driver will be reloaded
# and VDR restarted.
#
# In order to actually use this script you need to implement
# the functions DriverLoaded(), LoadDriver() and UnloadDriver()
# and maybe adjust the VDRPRG and VDRCMD to your particular
# requirements.
#
# Since this script loads the DVB driver, it must be started
# as user 'root'. Add the option "-u username" to run VDR
# under the given user name.
#
# 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.
