# Rules for generating marshal files using glib-genmarshal
#
# Define:
# 	glib_marshal_list = marshal list file
# 	glib_marshal_prefix = prefix for marshal functions
#
# before including Makefile.am.marshal. You will also need to have
# the following targets already defined:
#
# 	CLEANFILES
#	DISTCLEANFILES
#	BUILT_SOURCES
#	EXTRA_DIST
