37 #
38 # If ${VDR_RCADDON_FILE} is set install this file

42 # (in example vdr-femon this would be /usr/lib/vdr/rcscript/plugin-femon.sh)
43 #
44 # This file is sourced by the startscript when plugin is activated in /etc/conf.d/vdr
45 # It could be used for special startup actions for this plugins, or to create the
46 # plugin command line options from a nicer version of a conf.d file.
