# Generic plug-in Makefile for Shotwell standard plugins.
#
# Requires PLUGIN and SRC_FILES be set to the name of the plugin binary (minus extension) and that 
# the directory is registered in plugins.mk.
#
# To use, include this file in each plug-in directory's Makefile after setting appropriate variables.
# Also be sure that each plug-in has a dummy_main() function to satisfy valac's linkage.
#
# NOTE: This file is called from the cwd of each directory, hence the relative paths should be
# read as such.
