% ============= Figure, Table, etc inserts ==========

% Assumptions 
%   The form is described by three letters, eg "fig" or "tbl"
%   If the list file exists, the page info is written. 
%   \writelistfile must be defined 
%   \autonumber, \autoreference, \ref, \quietref, \veryraggedright
%   If autonumbering is on, then 
%      \silent, \autofignum ..
%   An "fig" form and "tbl" form are defined. These need 
%        \figurelabel, and \tablelabel respectively. These are
%        usually defined in the \englishversion and \versionfrancaise
%   The insert forms use \beginmidinsert ... \endmidinsert.

% This is a general form for an  insert with a caption, under it 
% if \topcaptionfalse and over it if \topcaptiontrue
% The particular form is identified with a (usually) three letter sequence
% such as "fig" or "tbl". There can be an associated list file for 
% automatic generation of the page list for the items. 
% The basic form is a non-floating type, enclosed in $$ ... $$ to give
% correct spacing. This can be put in an insert to make it float. 
% Full page forms require \vfill above and/or below for top, bottom, or center.

% The caption box measures its size and centers the text if it is short 
% or puts it in a \vbox which is \captiontextfraction of the \hsize 
% if it is not. 
% The \captionskip is the spacing between the caption and the actual 
% item in the text. This may be a table or figure or ....

% \let\captionnumfont = \bf
% \let\captiontextfont = \relax % defaults to "outside font"

% A caption is assumed to have both a &lt;title&gt; that will appear in the

% off when making lists.

%\def\figtocout{\string\figtoc} % actually set in inrsdef.tex 


% For Tables 
\def\tableform #1#2#3{\geninsertform {tbl}{#1}{#2}{#3}}
\def\tbllabel{\tablelabel }
\def\tableinsert #1#2#3{\beginmidinsert 
                         \tableform{#1}{#2}{#3}

% Comment ---- \endinsert in Plain has a pre and post \bigskip 
% This should probably be removed and the spacing always controlled by 
% the $$ ... $$. Instead, if the \everymidinsert form were used it 
% would be possible to remove it with \everymidinsert = {\let\bigskip=\relax</pre></body></html>
