# If you want to install extra packages (such as rpi or matlab), you need to have the environment

# EXTRA=rpi vagrant up

# EXTRA=rpi,matlab vagrant up

# If you don't want any submissions to be automatically generated for the courses created
# by vagrant, you'll want to specify NO_SUBMISSIONS flag.
