Makefile

# This makefile is defined to give you the following targets:
#
#    default: The default target: Compiles $(PROG) and whatever it 
#	   depends on.
#    style: Run our style checker on the project source files.  Requires that
#           the source files compile.
#    check: Compile $(PROG), if needed, and then for each file, F.in, in
#	   directory testing, use F.in as input to "java $(MAIN_CLASS)" and
#          compare the output to the contents of the file names F.out.
#          Report discrepencies.
#    clean: Remove all the .class files produced by java compilation, 
#          all Emacs backup files, and testing output files.
#
# In other words, type 'gmake' to compile everything; 'gmake check' to 
# compile and test everything, and 'gmake clean' to clean things up.
# 
# You can use this file without understanding most of it, of course, but
# I strongly recommend that you try to figure it out, and where you cannot,
# that you ask questions.  The Lab Reader contains documentation.
