# Note that this is _not_ what is in the `/usr/class/cs143` subdirectory in the
# VM! The `cs143` contains make files that generate the assignments in an
# arbitrary folder from skeleton files. Essentially this step was already done
# in the `student-dist.tar.gz`. The assignments just have to be completed and
# submitted in the respective /class/assignments/PA* subdirectories.
