\section{Status Bar}
\begin{table}
\begin{tagmap}{}{}
\config{\%we} & Status Bar Enabled\\
\config{\%wd} & Status Bar Disabled\\
\end{tagmap}
\end{table}
These tags override the player setting for the display of the status bar.
They must be noted on their own line.

\section{ID3 Info}
\begin{table}
  \begin{tagmap}{}{}
    \config{\%ia} & ID3 Artist\\
    \config{\%ic} & ID3 Composer\\

    \config{\%iy} & ID3 Year\\
  \end{tagmap}
\end{table}
Remember that this information is not always available, so use the 
conditionals to show alternate information in preference to assuming.

\section{Power Related Information}
\begin{table}
  \begin{tagmap}{}{}
    \config{\%bl} & Show numeric battery level in percent.\\
                  & Can also be used in a conditional:

           {\textbar}aac\-{\textbar}shn\-{\textbar}sid\-{\textbar}adx\-%
           {\textbar}unknown{\textgreater}}.\\

  \end{tagmap}
\end{table}
Example for the \config{\%dN} commands: If the path is 
``/Rock/Kent/Isola/11 - 747.mp3'', \config{\%d1} is ``Isola'', 
\config{\%d2} is ``Kent'' \dots{} You get the picture.

\section{Changing Volume}
\begin{table}
  \begin{tagmap}{}{}
    \config{\%mv[t]} & ``v'' if the volume is being changed\\
  \end{tagmap}
\end{table}

The tag produces the letter ``v'' while the volume is being changed and some
amount of time after that, i.e. after the volume button has been released. The
optional parameter \config{t} specifies that amout of time. If it is not
specified, 1 sec is assumed.

The tag can be used as the switch in a conditional tag to display different things
depending on whether the volume is being changed. It can produce neat effects
when used with conditional viewports.

Example: \config{\%?mv2.5{\textless}Volume changing{\textbar}\%pv{\textgreater}}

The example above will display the text ``Volume changing'' if the volume is
being changed and 2.5 secs after the volume button has been released. After
that, it will display the volume value.

\section{Settings}
\begin{table}
  \begin{tagmap}{}{}
    \config{\%St{\textbar}<setting name>{\textbar}} & Display the value of any Rockbox setting\\
  \end{tagmap}
\end{table}
Example: Can be used as a simple tag \config{\%St{\textbar}skip length{\textbar}} or with conditionals
\config{\%?St{\textbar}eq enabled{\textbar}{\textless}Equalizer is enabled{\textbar}Equalizer is disabled{\textgreater}}.

\section{Images}
\begin{table}
  \begin{tagmap}{}{}
    \nopt{archos}{%
    \config{\%X{\textbar}filename.bmp{\textbar}}
        & Load and set a backdrop image for the WPS.
          This image must be exactly the same size as your LCD.\\
    }%
    \config{\%P{\textbar}filename.bmp{\textbar}}
        & Load a Progress bar image for the WPS. Use \config{\%pb} tag to show the 
          progress bar\\
    \config{\%x{\textbar}n{\textbar}filename{\textbar}x{\textbar}y{\textbar}}
        & Load and display an image\\
        & \config{n}: image ID (a-z and A-Z) for later referencing in \config{\%xd}\\
        & \config{filename}: filename relative to \fname{/.rockbox/} and including .bmp\\
        & \config{x}: x coordinate\\
        & \config{y}: y coordinate.\\
    \config{\%xl{\textbar}n{\textbar}filename{\textbar}x{\textbar}y{\textbar}[nimages{\textbar}]}
        & Preload an image for later display (useful for when your images are displayed conditionally)\\
        & \config{n}: image ID (a-z and A-Z) for later referencing in \config{\%xd}\\
        & \config{filename}: filename relative to \fname{/.rockbox/} and including .bmp\\
        & \config{x}: x coordinate\\
        & \config{y}: y coordinate.\\
        & \config{nimages}: (optional) number of sub-images (tiled vertically, of the same height)
          contained in the bitmap. Default is 1.\\
    \config{\%xdn[i]} & Display a preloaded image\\
        & \config{n}: image ID (a-z and A-Z) as it was specified in \config{\%x} or \config{\%xl}\\
        & \config{i}: (optional) number of the sub-image to display (a-z for 1-26 and A-Z for 27-52).
          By default the first (i.e. top most) sub-image will be used.\\
  \end{tagmap}
\end{table}

Examples:
\begin{enumerate}
\item Load and display the image \fname{/.rockbox/bg.bmp} with ID ``a'' at 37, 109:\\
\config{\%x{\textbar}a{\textbar}bg.bmp{\textbar}37{\textbar}109{\textbar}}
\item Load a bitmap strip containing 5 volume icon images (all the same size)
with image ID ``M'', and then reference the individual sub-images in a conditional:\\
\config{\%xl{\textbar}M{\textbar}volume.bmp{\textbar}134{\textbar}153{\textbar}5{\textbar}}\\
\config{\%?pv<\%xdMa{\textbar}\%xdMb{\textbar}\%xdMc{\textbar}\%xdMd{\textbar}%
\%xdMe>}
\end{enumerate}


\note{
  \begin{itemize}
  \item The images must be in a rockbox compatible format (1 bit per pixel BMP)
  \item The image tag must be on its own line
  \item The ID is case sensitive, giving 52 different ID's
  \item The size of the LCD screen for each player varies. See table below 
        for appropriate sizes of each device. The x and y coordinates must 
        repect each of the players' limits.
  \end{itemize}

\section{Alignment}
\begin{table}
  \begin{tagmap}{}{}
    \config{\%al} & Text is left aligned\\
    \config{\%ac} & Text is center aligned\\
    \config{\%ar} & Text is right aligned\\
  \end{tagmap}
\end{table}
All alignment tags may be present in one line, but they need to be in the 
order left -- center -- right. If the aligned texts overlap, they are merged.

\section{Conditional Tags}

\begin{table}
\begin{tagmap}{}{}
\config{\%?xx{\textless}true{\textbar}false{\textgreater}}
    & If / Else: Evaluate for true or false case \\

                           displayed; see conditionals above). You can specify 
                           up to 10 scrolling lines. Scrolling lines can not 
                           contain dynamic content such as timers, peak meters
