The chess clock plugin is designed  to
simulate a chess clock, but it can be used
in any kind of game with up to ten players.

\subsubsection{Setup}

\begin{table}
  \begin{btnmap}{}{}
    \opt{PLAYER_PAD,IRIVER_H100_PAD,IRIVER_H300_PAD}{\ButtonRight/\ButtonLeft}
    \opt{RECORDER_PAD,ONDIO_PAD}{\ButtonUp/\ButtonDown}
    \opt{IPOD_4G_PAD}{\ButtonScrollBack/\ButtonScrollFwd}
      & Increase / Decrease displayed Value\\
    \opt{PLAYER_PAD,RECORDER_PAD}{\ButtonPlay}
    \opt{IRIVER_H100_PAD,IRIVER_H300_PAD}{\ButtonOn}
    \opt{ONDIO_PAD}{\ButtonRight}
    \opt{IPOD_4G_PAD}{\ButtonSelect}
      & Move to next screen\\
    \opt{PLAYER_PAD}{\ButtonStop}
    \opt{ONDIO_PAD,IPOD_4G_PAD}{\ButtonMenu}
    \opt{RECORDER_PAD,IRIVER_H100_PAD,IRIVER_H300_PAD}{\ButtonOff}
      & Move to next screen\\
  \end{btnmap}
\end{table}

\begin{itemize}
  \item First enter the number of players (1--10)
  \item Then set the total game time in mm:ss
  \item Then the maximum round time is entered.  For example, this could
  be used to play Scrabble for a maximum of 15 minutes each, with each
  round taking no longer than one minute.
  \item Done. Player 1 starts in paused mode.
\end{itemize}

\subsubsection{While playing}
The number of the current player is displayed on the top line. The time
below is the time remaining for that round (and possibly also the total
time left if different). 

Keys are as follows:

\begin{table}
  \begin{btnmap}{}{}

    \opt{RECORDER_PAD,ONDIO_PAD}{\ButtonOff}
    \opt{IRIVER_H100_PAD,IRIVER_H300_PAD}{\ButtonSelect}
    \opt{IPOD_4G_PAD}{\ButtonPlay}
      & Exit plugin \\
    \opt{PLAYER_PAD}{\ButtonStop}

    \opt{PLAYER_PAD,RECORDER_PAD}{\ButtonPlay}
    \opt{IRIVER_H100_PAD,IRIVER_H300_PAD}{\ButtonOn}
    \opt{ONDIO_PAD}{\ButtonRight}
    \opt{IPOD_4G_PAD}{\ButtonSelect}

    \opt{PLAYER_PAD,IRIVER_H100_PAD,IRIVER_H300_PAD}{\ButtonRight}
    \opt{RECORDER_PAD,ONDIO_PAD}{\ButtonUp}
    \opt{IPOD_4G_PAD}{\ButtonScrollBack}
      & Switch to next player \\
    \opt{PLAYER_PAD,IRIVER_H100_PAD,IRIVER_H300_PAD}{\ButtonLeft}
    \opt{RECORDER_PAD,ONDIO_PAD}{\ButtonDown}
    \opt{IPOD_4G_PAD}{\ButtonScrollFwd}
      & Switch to previous player \\
    \opt{PLAYER_PAD,ONDIO_PAD,IPOD_4G_PAD}{\ButtonMenu}
    \opt{RECORDER_PAD}{\ButtonFOne}
    \opt{IRIVER_H100_PAD,IRIVER_H300_PAD}{\ButtonRec}
      & Delete current player %
      \opt{PLAYER_PAD,RECORDER_PAD}{(\ButtonPlay\ to confirm.)}
      \opt{IRIVER_H100_PAD,IRIVER_H300_PAD}{(\ButtonOn\ to confirm.)}
      \opt{ONDIO_PAD}{(\ButtonRight\ to confirm.)}
      \opt{IPOD_4G_PAD}{(\ButtonSelect\ to confirm.)}\\
  \end{btnmap}
\end{table}
From the menu it is possible to delete a player, modify the round time
for the current player or set the total time for the game. 

When the round time is up for a player the message ``ROUND UP!'' is shown (press  NEXT to continue). 

When the total time is up for a player the message ``TIME UP!''is shown. Then player will  then be removed from the timer.
