%\newpage\section{Usage}
% At this moment, there are three float environments done here:
% |table|, |figure| (with their starred and sub... forms) and |algorithm|.
%                                  
%
% In order to facilitate customization, the following commands are
% exported:
%
% \def\pitem[#1]{\item[\ttfamily\string #1]\SpecialUsageIndex{#1}}
%\begin{description}
%\pitem[\tabwidth]  Allows setting the width of a table that has to be
%centered, but does not contain a |tabular| or |TABULAR|. Also,
%it might be handy for tables that contain more than one |tabular|.
%(e.g. |\tabwidth{20pc}|)                                             
%\pitem[\tabfont]  Font specification for the main text of tables.\\
%           (default value |\footnotesize|)
%\pitem[\tabcapfont]  Font specification for table captions.
%               (default value |\footnotesize|)
%\pitem[\figcapfont]  Font specification for caption of figures. There is no
% definition for the font of the text of figures.
%               (defaultvalue |\footnotesize|)
%\pitem[\tableindent] Indentation for tables. 
%               (default given by stylefile)
% Tables and figures can be either indented over a specified width, or
% centered. This can be done independent of each other, but both
% always use the same indentation. i.e: You cannot
% have figures indented 4 picas and tables 2 picas, but you can have
% indented tables with centered figures.
%\pitem[\figindent] Indentation for figures. From the note above for these
%two commands it follows that if both are given, they have to set the same
% value. If they don't, the last given value will prevail.
%               (default given by stylefile)
%\pitem[\figtabdot] The dot after the number. (default value |.|)         
%\pitem[\captionskip] Vertical skip between caption and main body of float.
%           (default value 6pt)
%\pitem[\tabcapspace] Space between heading of caption and
%text of caption. This is a vertical or horizontal skip, depending on
%whether captions are split or not. Default value .5em.
%\pitem[\splittabcaptions] Splits the table captions in two parts.
%\pitem[\splitfigcaptions] Splits the figure captions in two parts.
%\pitem[\splitcaptions] Combines both.
%\pitem[\indentedcaptions] Ordinarily, captions are centered above or below
%the float. This setting allows you to specify a specific indentation. 
%\pitem[\captionindent] Value used for the previous option The default value
%is 0pt (appears to make most sense).

%\newpage\section{Implementation}
%
% The |klutab| is necesarry here, because we need the definitions 
% of tabular \& co that set the correct widths. It also makes sure that
% these two are nicely tied in to eachother (version control problems).
%

\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{klufloa}[\filedate ]
\RequirePackage{klutab}[1997/05/30]

%\subsection{Float parameters}
% These are standard as in \LaTeXe.
%    \begin{macrocode}
\setcounter{topnumber}{2}
\setcounter{bottomnumber}{1}
\setcounter{totalnumber}{3}
\setcounter{dbltopnumber}{2}
%    \end{macrocode}
% The parameters below try to ensure that there are not so many float
% pages. (prevents empty white space). 
%
% In the old stylefiles, 
% |\topfraction| was $.99$, but that was bit to much, resulting in
% pages with a huge float and only two text lines. Now a float has
% to be $>.85$|\textheight| before it will result in a float page.
% (oversimplified, but this is the general idea). This leaves
% space on the page for a few more textlines.
%
% |\bottomfraction| used to be $.3$,  but that is to small for almost 
% any float this style generates; there are split captions and tabnotes
% to account for, so the value has increased a bit.

% |\figtabdot| serves the same purpose as |\sectiondot| elsewhere,
% and the 
% names of various strings.

\def\figtabdot{.}
\def\tablename{Table}%
\def\figurename{Figure}%
\def\algorithmname{Algorithm}%
%    \end{macrocode}
% |\maxfloatwidth| is the allowed width of the table.\\
% (If this is a rotated table or figure, it will use all of the
% page. Of course, |\maxfloatwidth| then is |\textheight|.)\\
% |\figtabbox| will contain the total float as a vbox.
% |\floatindent| is the indentation skip for indented tables \& figures. 
% The last defined value will overwrite the previous one.\\
% |\@tabskip| is an aid in helping to decide indentation of rotated tables.\\
% |\cap@type| is an aid in keeping track of caption types\\
% |\captionskip| is the vertical skip between caption and main body.
%    \begin{macrocode}

%
% |\@tabwidth| is
% supposed to contain the width of the table. (the width of |\figtabbox| is
% probably either |\textwidth| or zero.) |tabular| and |TABULAR| from 
% |klutab.sty| set
% this value automatically, but so should every |table|. If your table
% does not contain a |tabular|, you can set this value yourself:
% just say |\tabwidth{..}| somewhere in your table.  Your text will
% be typeset inside a |\vbox| with width |\maxfloatwidth|.

% It is called from figure and table. 
%
% For rotated floats, |\maxfloatwidth| == |\vsize|. The use
% of |\vsize| here is probably 
% better than |\textheight|, because it allows use of minipages and
% |\vbox|es to get special effects (where |\textheight| $>$ |\vsize|).
%
% |\@floatcorrect| fixes indentation for rotated floats. This and\\
% |\hbox@to@floatwidth| are just shortcuts.

% |\@getindent| calculates the values for |\@tabskip| and

% \subsubsection{Rotation macros}
% These are used in the |kaprotate| environment. Note that these
% macros depend on PostScript output at this moment. Later,
% I might include commands for (at least) Tpic.
%
% These are just a few macro's, so it isn't really worth including |graphicx|
% at the moment.
%
% |\rotl| and |\rotr| rotate a given box over resp. 270 and 90 degrees
% while typesetting that box. The new box has $wd_{new}=dp_1 + ht_1$ and
% $ht_{new}=wd_1$, with $dp_{new} ==0$.
