% The type size option is handled by reading a different file for each
% size, as follows, to define font size-specific commands:
% 10pt : REP10, 11pt : REP11, 12pt : REP12
% Implemented by \def'ing \@ptsize to last digit of file name.
%
\def\@ptsize{0} % Default is REP10.STY
\@namedef{ds@11pt}{\def\@ptsize{1}} % 11pt option reads in REP11.STY
\@namedef{ds@12pt}{\def\@ptsize{2}} % 12pt option reads in REP12.STY
% Two-side or one-side printing.
%
% \@twosidefalse % Default is one-sided printing.
\def\ds@twoside{\@twosidetrue % Defines twoside option.
\@mparswitchtrue} % Marginpars go on outside of page.
% draft option
%
% \overfullrule = 0pt % Default is don't mark overfull hboxes.
\def\ds@draft{\overfullrule 5pt} % Causes overfull hboxes to be marked.
% The \@options command causes the execution of every command \ds@FOO
% which is defined and for which the user typed the FOO option in his
% \documentstyle command. For every option BAR he typed for which
% \ds@BAR is not defined, the file BAR.sty will be read after the present
% (main) .STY file is executed.

%
% A \subsection command writes a
% \contentsline{subsection}{TITLE}{PAGE}
% command on the .toc file, where TITLE contains the contents of the
% entry and PAGE is the page number. If subsections are being numbered,
% then TITLE will be of the form
% \numberline{NUM}{HEADING}
% where NUM is the number produced by \thesubsection. Other sectioning
% commands work similarly.
%
% A \caption command in a 'figure' environment writes
% \contentsline{figure}{\numberline{NUM}{CAPTION}}{PAGE}
% on the .lof file, where NUM is the number produced by \thefigure and
% CAPTION is the figure caption. It works similarly for a 'table' environment.
%
% The command \contentsline{NAME} expands to \l@NAME. So, to specify
% the table of contents, we must define \l@chapter, \l@section,
% \l@subsection, ... ; to specify the list of figures, we must define
% \l@figure; and so on. Most of these can be defined with the
% \@dottedtocline command, which works as follows.
%
% \@dottedtocline{LEVEL}{INDENT}{NUMWIDTH}{TITLE}{PAGE}
% LEVEL : An entry is produced only if LEVEL < or = value of
% 'tocdepth' counter. Note, \chapter is level 0, \section
% is level 1, etc.
% INDENT : The indentation from the outer left margin of the start of
% the contents line.
% NUMWIDTH : The width of a box in which the section number is to go,
% if TITLE includes a \numberline command.
%
% This command uses the following three parameters, which are set
% with a \def (so em's can be used to make them depend upon the font).
% \@pnumwidth : The width of a box in which the page number is put.
% \@tocrmarg : The right margin for multiple line entries. One
% wants \@tocrmarg > or = \@pnumwidth
% \@dotsep : Separation between dots, in mu units. Should be \def'd to

% \footnoterule is a macro to draw the rule separating the footnotes from
% the text. It should take zero vertical space, so it needs a negative
% skip to compensate for any positive space taken by the rule. (See
% PLAIN.TEX.)

\kern 2.6\p@} % The \hrule has default height of .4pt .
% \newcounter{footnote}
\@addtoreset{footnote}{chapter} % Numbers footnotes within chapters
% \@makefntext{NOTE} :
% Must produce the actual footnote, using \@thefnmark as the mark
% of the footnote and NOTE as the text. It is called when effectively
% inside a \parbox of width \columnwidth (i.e., with \hsize =
% \columnwidth).
%
% The following macro indents all lines of the footnote by 10pt, and
% indents the first line of a new paragraph by 1em. To change these
% dimensions, just substitute the desired value for '10pt' [in both
% places] or '1em'. The mark is flushright against the footnote.

%
% A simpler macro is used, in which the footnote text is
% set like an ordinary text paragraph, with no indentation except
% on the first line of a paragraph, and the first line of the
% footnote. Thus, all the macro must do is set \parindent
% to the appropriate value for succeeding paragraphs and put the
% proper indentation before mark.

% To define a float of type TYPE (e.g., TYPE = figure), the document style
% must define the following.
%
% \fps@TYPE : The default placement specifier for floats of type TYPE.
%
% \ftype@TYPE : The type number for floats of type TYPE. Each TYPE has
% associated a unique positive TYPE NUMBER, which is a power
% of two. E.g., figures might have type number 1, tables type
% number 2, programs type number 4, etc.
%
% \ext@TYPE : The file extension indicating the file on which the
% contents list for float type TYPE is stored. For example,
% \ext@figure = 'lof'.
%
% \fnum@TYPE : A macro to generate the figure number for a caption.
% For example, \fnum@TYPE == Figure \thefigure.
%
% The actual float-making environment commands--e.g., the commands
% \figure and \endfigure--are defined in terms of the macros \@float
% and \end@float, which are described below.
%
% \@float{TYPE}[PLACEMENT] : Macro to begin a float environment for a
% single-column float of type TYPE with PLACEMENT as the placement
% specifier. The default value of PLACEMENT is defined by \fps@TYPE.
% The environment is ended by \end@float.
% E.g., \figure == \@float{figure}, \endfigure == \end@float.
