USAGE="Usage: $0 [-hknv] [-t terminal] workspace? [-- terminal...]

    The workspace can be passed either on the command line
    or in the WS environment variable (=$WS).  If it workspace isn't
    specified, the terminal is created on the current workspace,
    but does not have a workspace ID embedded in its name.
