To share your screen, use the following command:

    $ pb152 beamer

To follow on your own screen, use:

    $ pb152 follow

In case you are visiting (i.e. not enrolled in this group) use:

    $ pb152 follow --login xlogin

where ‹xlogin› is the login name of the student whose screen is being beamed.
You can often see this login name on the beamer (part of the shell prompt). If
unsure, please ask.

More detailed instructions are available in ‹../01/activity.txt›.
