%    LEVEL      : a number, denoting depth of section -- e.g., chapter=1,
%                 section = 2, etc.  A section number will be printed if

%                 counter.
%    INDENT     : Indentation of heading from left margin
%    BEFORESKIP : Absolute value = skip to leave above the heading.
%                 If negative, then paragraph indent of text following
%                 heading is suppressed.
%    AFTERSKIP  : if positive, then skip to leave below heading,
%                       else - skip to leave to right of run-in heading.
%    STYLE      : commands to set style
%  If '*' missing, then increments the counter.  If it is present, then
%  there should be no [ALTHEADING] argument.  A sectioning command
%  is normally defined to \@startsection + its first six arguments.

% 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,

% \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.)

\def\footnoterule{\kern-1\p@
  \hrule width .4\columnwidth
  \kern .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.
%
%        It is much easier to write a macro 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.  In that case, 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
%                content<s 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.
