# Usage:

#   $ make test     # run tests
#   $ make clean    # remove intermediate files
#
# --- notes -------------------------------------------------
#
# See http://www.gnu.org/software/make/manual/make.html
#
# Basically, a Makefile like this contains compilation rules, which
# let the "make" program figure out what needs to be recompiled
# depending on what has changed.
#
# explict rules : 
#
#    target_file : depends_file_1 depends_file_2
#             command that creates target_file from dependencies
#
# special rules
#
#     all: target1 target2 target 3    # what needs to be created
#
#     clean: 
#        what to do to remove intermediates
#
#     test:
#        how to run reality checks
#
# other
#
#     CC by default is the name of the C compiler; defaults to cc
#     CFLAGS by default are c compiler options
#
#     -lm is "-lib math" which is needed if <math.h> is included.
