Please see the Project 0 submission instructions.
The only difference is that you should submit your project3
directory, and specify 3 as the argument to the submit script; i.e.:
cd project3/build
gmake clean
cd ../../
tar cvf proj3.tar project3
gzip proj3.tar
/afs/csic.umd.edu/submit/fall2005/cmsc412/bin/submit 3 proj3.tar.gz
