[lug] How do you setup a recursive make?

[bdoctor at ps-ax.com]

Here is an applicable stub:

SUBDIRS = lib server client docs 

        list='$(SUBDIRS)'; for subdir in $$list; do \
          echo "Making $$target in $$subdir"; \
          (cd $$subdir && $(MAKE) $(MAKEFLAGS) $$target) \ 

Order is important, in terms of library dependency.
