# $Id$

# The official name of this plugin.
# This name will be used in the '-P...' option of VDR to load the plugin.
# By default the main source file also carries this name.
# IMPORTANT: the presence of this macro is important for the Make.config
# file. So it must be defined, even if it is not used here!
