# 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
#
# Author: Emmanuele Bassi <ebassi@linux.intel.com>
# Basic sanity checks
