     DESCRIPTION
          These commands are wm(1) programs that are clients of the
          services of collabsrv(8). It must therefore be running in
          the network for any of them to be usable.  Furthermore,
          collabsrv's service directory must appear somewhere in the
          client's name space, for instance by using connect(1),
          although plain mount (see bind(1)) can also be used.  In all
          cases, the optional parameter servicedir names the service
          directory (default: /n/remote/services).  Finally, collabsrv
          must be configured to provide the service.

          Chat is a simple multi-user chat program.  Each user that
          wishes to chat starts chat naming the desired chatroom,
          which is an identifying string agreed amongst the clients.
          (It is often convenient to use the path name of a shared
          file.)  Chat attempts to enter the given chatroom. It
          announces the results of the connection, and if successful,
          displays subsequent chat room messages.  Its window provides
          a scrollable text area that forms a transcript of the cur-
          rent conversation, and a single line of editable text at the
          bottom of the window for sending messages.  Messages sent by
          others appear in the transcript tagged with the sender's
          name.  When the user types a new line (return, enter) in the
          text entry area, chat sends the text to all the members of
          the chat room, and it subsequently appears in the user's own
          transcript, tagged with <you> in place of the user's name.
          Chat also notes in the transcript the arrival and departure
          of other users.

          Poll and poller together enable simple real-time polls.  One
          user runs poller, which activates the given polling station.
          The other users can subsequently join using poll, naming the
          same station, and can come and go as they please as long as
          the poller remains.  The polling station closes when the
          poller leaves.

          Poller drives the interaction for a sequence of one or more

          real-time polls.  It is assumed that the poller is in the
          same room as those polled, allowing the questions and
          answers to be read out each time, as in quiz shows and exit
          polls.  Alternatively, something like chat could be used to
          pose questions to a distant audience.  For each poll, the
          polling user selects, in poller's window, the number of pos-
          sible answers (2, 3, or 4) using radio buttons, and hits the
          Start button.  A bar chart shows results as they come in:
          each bar shows the percentage of those polled (thus far)
          that have selected the corresponding alternative.  Once the
          polling user hits Stop, no further results are accepted, and
          the bar chart represents the final result.  The -d option
          causes poller to display a debugging transcript of the mes-
          sages it receives.

          Each user being polled runs poll, and initially sees an
          array of radio buttons with labels A, B, C and D.  They
          remain disabled until the poller hits Start, at which point
          poll enables as many radio buttons as allowed by the poller
          for this round.  If the user selects a button, poll immedi-
          ately send the selection to the polling station (and thus to
          the poller), and disables all the buttons, although the
          user's selection remains marked.  All buttons are also dis-
          abled when the poller says to stop, whether or not a choice
          has been made.  Buttons are enabled again at the start of
          the next question.  The -d option causes poll to display a
          debugging transcript.

          Whiteboard allows several users to draw on the shared canvas
          with the given id, which is an identifying string agreed
          amongst the clients.  The whiteboard window contains a can-
          vas to be drawn on with stylus, or mouse button 1.  Strokes
          drawn in a given whiteboard appear in all others with the
          same board id. There are two controls at the bottom of the
          window: the lower left-hand corner has a small pop-up menu
          of brush shapes, including one for erasing; and a long
          coloured button showing the current drawing colour that pops
          up a choice of drawing colour from a palette.  Artists can
          come and go as they please, but the drawing vanishes for
          ever when the last artist leaves the whiteboard.
