# This is a simple script that takes a sequence of command-line arguments
# that are names of test input files, and for each value F.trk in this
# sequence, runs 
#   java tracker.Main F.trk F.out
# Then if F is a file whose name begins with 'bad', the script checks that
# it exits with a nonzero exit code and prints an error message in the proper
# form.  Otherwise, it runs
#   diff -b F.std F.out
# to check for the right output. It counts up and reports the number of
# failures and successes. 
# 
# Feel free to adapt it to your needs.
