# NOTE:  The natural random numbers in "randfile" are accessed by the
# 'rand' module via a path to this directory.  Change the definition of
# RAND_FILE in the compilation command for rand.c below if this is not
# appropriate.

# NOTE:  This makefile is trivial, simply recompiling everything from
# scratch every time.  Since this takes only about 5 seconds on a modern
# PC, there's no point in putting in dependency-based rules, which just 
# make things more complex and error-prone.
