# VDR shutdown hook for nvram-wakeup - Tobias Grimm <tg@e-tobi.net>
# ----------------------------------

# This shutdown hook sets the wakeup time for the next timer using
# nvram-wakeup. If necessary the shutdown command is modified to
# use a special shutdown strategy.

[ -z "$ENABLED" ]           && export ENABLED="no"
