# Rules for generating enumeration types using glib-mkenums
#
# Define:
# 	glib_enum_h = header template file
# 	glib_enum_c = source template file
# 	glib_enum_headers = list of headers to parse
#
# before including Makefile.am.enums. You will also need to have
# the following targets already defined:
#
# 	CLEANFILES
#	DISTCLEANFILES
#	BUILT_SOURCES
#	EXTRA_DIST
