# To be included by the top-level Makefile in the program's directory.
# The caller must define
# 
#   ${SUBDIRS} a list of sub-dirs of current dir where "make" needs to run
#
# "make XXX" will perform "make XXX" on each of the ${SUBDIRS}, in order.

include GENERIC.make

# ----------------------------------------------------------------------
# "make actions" performs all of the ${ACTIONS} in each subdir, in turn:

actions: 
	for dir in ${SUBDIRS}; do \
          ( echo '= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = ='; \

            cd $$dir/. && \
            make ACTIONS="${ACTIONS}" actions ; \
          ) ; \
        done

# "make build-progs"

# These actions are just performed on all sub-directories in the 
# client-defined list ${SUBDIRS}, in order.
