#
# Makefile for a Video Disk Recorder plugin
#
# $Id$

# 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!
#
PLUGIN = softhddevice

### The version number of this plugin (taken from the main source file):

VERSION = $(shell grep 'static const char \*const VERSION *=' $(PLUGIN).cpp | awk '{ print $$7 }' | sed -e 's/[";]//g')
GIT_REV = $(shell git describe --always 2>/dev/null)
