[vdr] runvdr in python

[Uberto Barbini <uberto@ubiland.net>]

I translated runvdr script in python.
I did so because I know python much better than bash and I need
messing often with it.
I added a feature so when vdr crash 3 times in a row (less than 30 sec
between crashes) runvdr quits.
It save me a lot of "killall runvdr" when drivers are broken!

I publish it here in case someone else may find it useful.

#!/usr/bin/python

# 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.
#
# Uberto: 
# 18-apr-2003 rewrite runvdr in python from bash script
# 30-apr-2003 print vdr exit value
# 01-may-2003 check and exit if vdr restart 3 times in a row
