# assumptions/caveats:
# - this script is run by bash 3.2+, produces a Makefile suitable for gnu make 3.81+
# - targets to build have a main function in a .c file of the same name
# - each module depended upon is in the same directory
# - each module depended upon consists of one .c and one .h file
# - if you need to link in external libraries, you still need to manually provide those to make via LDLIBS
