% CHOOSING THE TYPE SIZE:
%
% The type size option is handled by reading a different file for each 
% size, as follows, to define font size-specific commands:
% 10pt : BK10, 11pt : BK11, 12pt : BK12
% Implemented by \def'ing \@ptsize to last digit of file name.
%

\def\@ptsize{0} % Default is speech10.STY
\@namedef{ds@11pt}{\def\@ptsize{1}} % 11pt option reads in speech11.STY
\@namedef{ds@12pt}{\def\@ptsize{2}} % 12pt option reads in speech12.STY

% 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

% \ds@BAR is not defined, the file BAR.sty will be read after the present

% 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{INDENT}{NUMWIDTH}{STYLE}{NUMBER}{TITLE}{PAGE}
% 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 &gt; or = \@pnumwidth
% \@dotsep : Separation between dots, in mu units. Should be \def'd to
% a number like 2 or 1.7

% \footnoterule is a macro to draw the rule separating the footnotes from

% 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.

% set like an ordinary text paragraph, with no indentation except

% 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.

%    ****************************************
%
% The page style 'foo' is defined by defining the command \ps@foo.  This
% command should make only local definitions.  There should be no stray
% spaces in the definition, since they could lead to mysterious extra
% spaces in the output.
%
% The \ps@... command defines the macros \@oddhead, \@oddfoot,
% \@evenhead, and \@evenfoot to define the running heads and
% feet---e.g., \@oddhead is the macro to produce the contents of the
% heading box for odd-numbered pages.  It is called inside an \hbox of
% width \textwidth.
%
% To make headings determined by the sectioning commands, the page style
% defines the commands \chaptermark, \sectionmark, ... , where
% \chaptermark{TEXT} is called by \chapter to set a mark, and so on.
% The \...mark commands and the \...head macros are defined with the
% help of the following macros.  (All the \...mark commands should be
% initialized to no-ops.)
%
% MARKING CONVENTIONS:
% LaTeX extends TeX's \mark facility by producing two kinds of marks
% a 'left' and a 'right' mark, using the following commands:
%     \markboth{LEFT}{RIGHT} : Adds both marks.
%     \markright{RIGHT}      : Adds a 'right' mark.
%     \leftmark  : Used in the \@oddhead, \@oddfoot, \@evenhead or \@evenfoot
%                  macro, gets the current 'left'  mark.  Works like TeX's 
%                  \botmark command.
%     \rightmark : Used in the \@oddhead, \@oddfoot, \@evenhead or \@evenfoot
%                  macro, gets the current 'right'  mark.  Works like TeX's 
%                  \firstmark command.
% The marking commands work reasonably well for right marks 'numbered 
% within' left marks--e.g., the left mark is changed by a \chapter command and
% the right mark is changed by a \section command.  However, it does
% produce somewhat anomalous results if two \bothmark's occur on the same page.
% 
% 
% Commands like \tableofcontents that should set the marks in some page styles
% use a \@mkboth command, which is \let by the pagestyle command (\ps@...)
% to \markboth for setting the heading or \@gobbletwo to do nothing.
