# What happens:
#
# The Makefile uses all items in SIM_NAMES to call the OBJECT_COLLECT_TEMPLATE 
# sequentially. This macro uses the sim name (e.g. ECLIPSE) as prefix for 
# the variables it is working on.
# It looks if there's a ..._SRC_DIR and ..._OBJ_DIR. 
# If not, it assigns both from ..._DIR.
# So you can also specify a single source and object directory with ..._DIR.
# 
# The template also builds a complete list of source files, ..._SOURCES.
#
# Then the OBJECT_RULE_TEMPLATE is expanded for all source files.
# The current object file name is created from the source file name,
# then added to the list of object files, ..._OBJS. 
# And, of course, the build rule for the object is output.
# After the expansion of the OBJECT_RULE_TEMPLATE, the ..._EXTRA_OBJS
# are added to the ..._OBJs list.
#
# There's another template, PROGRAM_TEMPLATE. It is called with all
# SIM_NAMES as well. It generates the link rules for each application,
# uses the ..._OBJS variable as input.
# It also generates a "phony" target with the executable's stem,
# to enable things like "make nova".
# The application clean rules, like "novaclean", are also created by means
# of this template.


# This tells make to use the ECLIPSE_ variables.
SIM_NAMES+=ECLIPSE

# The program's source directory
ECLIPSE_SRC_DIR=NOVA

# Where the program's modules go to
ECLIPSE_OBJ_DIR=eclipse

# to delete with "make clean".

# be generated. The common parts leave this blank.
