# This a Makefile, an input file for the 'make' program.  For you 
# command-line and Emacs enthusiasts, this makes it possible to build
# this program with a single command:
#     gmake 
# (or just 'make' if you are on a system that uses GNU make by default,
# such as Linux.) You can also clean up junk files and .class files with
#     gmake clean
# To run style61b (our style enforcer) over your source files, type
#     gmake style
# Finally, you can run any tests you'd care to with
#     gmake check
# This first runs your program on the input files tests/*.inp and checks
# to see that it completes normally and that the results are those in the
# files tests/*.out.  It also runs the program on the input files tests/*.err
# and checks that the program properly reports an error as given in the
# specification. It's up to you to come up with the test files; the 
# skeleton just includes some simple samples.

# On the instructional machines, we've defined the environment variable
# $STAFFLIBDIR to be ~cs61b/lib, where we keep .jar (Java Archive) files
# containing staff classes.  At home, you can define STAFFLIBDIR to point at
# wherever you keep copies of these files.

# Flags to pass to Java compilations (include debugging info and report
# "unsafe" operations.)
