   4 #MORE = path to supplementary needed resources not linked from MAIN
   5 #NAME = name of project (used for jar output file)
   6 #PREFIX = usually /usr/local (where to install the program)
   7 #TEST = path to main test source to compile
   8 #JAR_FLAGS += a list of things to pack, each usually prefixed with "-C bin/"

  24 #       make clean      : to clean the directory of intermediate files
  25 #       make mrpropre   : to clean the directory of all outputs
  26 #       make run        : to run the program from the binaries
