# Automatically added by dh_vdrplugin_enable/UNDECLARED
#
# To enable a vdr plugin, its config must be symlinked to /etc/vdr/conf.d.
# This must only be done when installing a plugin package or upgrading
# from an old package, which does not support the conf.d mechanism.
#
# Before installing, we remember if the plugin-config in conf.avail
# does not exist (because this is a new installation or an upgrade
# from an old installation or the config was removed by the admin)
# by creating a /etc/vdr/conf.d/*.dpkg-vdr-plugin-enable "tag"-file.
