# DESCRIPTION
#
# This file is included by every Makefile in the WindML build.
# This file contains makefile rules that are host independent for creating
# windML libraries. 
#
# INCLUDES
#	include $(WINDML_CONFIG_DIR)/$(WINDML_CONFIG_NAME)_makefile
#	include $(TGT_DIR)/h/make/defs.default
#       include $(TGT_DIR)/h/make/make.$(CPU)$(TOOL)
#	include $(TGT_DIR)/h/make/defs.$(WIND_HOST_TYPE)
#
# The build targets supported for maintaining the WindML are:
#
# targets for maintaining the ugl archive.
#
#  ugl (default)- 
#        Compiles each modified file and updates the ugl archive with 
#        with the new object files
#
#  uglrclean/rclean - 
#        Recursively removes each object file and deletes the archive.  
#            
#
#  uglclean/clean - 
#        Removes each object file in the current directory
#
#
#
# Build targets for maintaining the WindML demonstration programs
#
#  ugldemo - 
#       Compiles each modified demo program creating a demo.o and a
#       demo_ugl.o object file where the demo_ugl.o file also contains
#       the WindML components
#
#  ugldemoclean - 
#       Removes all the demonstration program object files
