-% \subsection{Modifying the caption command}
-%
-% \begin{macro}{\@caption}
-% |\caption| just saves its main argument in a token register. It also
-% has |\unskip| and |\ignorespaces| to cope with hmode.
-% The format of the token register is:\\
-% \marg{type}\marg{number}\marg{caption text}\marg{extra info}\\
-% The \meta{type} is something like `figure', used to generate the
-% relevant command names. \meta{number} is the fully expanded version of
-% |\the|\ldots. The last group is unused by the current definition
-% but extended packages may use it to pass extra information to the
-% float handler, as required.
-% \begin{macrocode}
-\def\caption{\@dblarg{\@caption\float@type}}
-
-\long\def\@caption#1[#2]#3{%
- \unskip
-% \end{macrocode}
-% We use the old \LaTeX{} interface with |\addcontentsline| for the
-% moment.\footnote{FIX!!}
-% \begin{macrocode}
- \addcontentsline{\csname toc@extension@#1\endcsname}{#1}
-% \end{macrocode}
-% The counter used is not |#1| but given by (|\foat@counter|) which
-% should perhaps be passed along but isn't:
-% \begin{macrocode}
- {\protect\numberline{\csname the\float@counter\endcsname}
- {\ignorespaces #2}}
- \global\toks\@currbox{#3}

-% \subsection{Adding captions to float boxes}
-%
-% This should really be a template instance.
-% Must \emph{copy} the float body in |\this@float@box|
-% into |\this@captioned@float| adding the caption text.
-% May use |\this@area|, |\this@area@col@number| and other information, to be
-% determined \ldots
-%
-% \begin{macro}{\append@caption@to@float}
-% Combine float body and caption of the current float (``this
-% float'') and store it in |\this@captioned@float|.

-% \section{Some primitive templates for testing}
-%
-% prove of concept only --- not even prototype
-%
-%
-% \begin{macro}{\typeset@some@floatbox}
-% The macro |\typeset@some@floatbox| take 7 arguments as follows:
-% \begin{description}
-% \item[type] type of the float to be typeset
-% \item[area] area in which to format the float
-% \item[floatbody box] box register in which the body of the float
-% is stored
-% \item[caption heading] fixed text like ``Figure''
-% \item[caption number] caption number of the float
-% \item[caption text] caption text of the float
-% \item[span count] span count (normally deducable from the area
-% but\ldots
-% \end{description}
-% The first two arguments are used to decide which formatting
-% instance to call, the remaining arguments are passed to that
-% instance.
-%
-% The logic is (at the moment) as follows: if a template instance
-% (type \texttt{buildfloat}) with the name
-% \meta{type}|-|\meta{area}\footnote{The ``here'' areas are
-% denoted as \texttt{h}\meta{col}\texttt{1}.}
-% is defined then this instance is used,
-% otherwise we look if there is an instance with just the name of
-% the \meta{area}, otherwise we try an instance with the name
-% \meta{type} and if this isn't defined either we try the instance
-% named |default|.
