# or directories to the main system.
# $(TARGETS) is the list of the main targets used to build the system,
# it contains all the directories recursed by the main Makefile, and the
# special target libgkern.a, that contains the base system.  To add a
# directory that specifies its own libraries simply put it in $(TARGETS).

# $(LIBGKERN-OBJS) is the list of targets that compose libgkern.a.  To
# add a directory to it, simply put it here.  The generic kernel used to
# be separed from the oslib and from the modules, but that hardly made
# sense for a Shark application, as all those three components are needed
# for it to run.
