% PREPARING A FOREIGN LANGUAGE VERSION:
%
% This document style is for documents prepared in the English language.
% To prepare a version for another language, various English words must
% be replaced.  All the English words that required replacement are
% indicated below, where we give the name of the command in which the
% words appear, and the entire line containing the word(s), with the
% actual words underlined.

%  ****************************************
%
% All margin dimensions measured from a point one inch from top and side
% of page.  Dimensions shrink by about 2 percent

% DRIVER MARGINS: change these to shift the complete page image as a whole
% on the page without modifying the layout

\voffset        0pt      % does not have to be -0.65in  since topmargin is -ve
\hoffset        0pt

% SIDE MARGINS:
   \oddsidemargin  -0.1in   %  Note that \oddsidemargin = \evensidemargin
   \evensidemargin -0.1in

% VERTICAL SPACING:
                         % Top of page:
\topmargin -55pt         %    Nominal distance from top of page to top
                         %    of box containing running head.
\headheight 12pt         %    Height of box containing running head.
\headsep 25pt            %    Space between running head and text.
% \topskip = 10pt        %    '\baselineskip' for first line of page.
                         % Bottom of page:
\footskip 60pt           %    Distance from baseline of box containing
                         %    foot to baseline of last line of text.


% DIMENSION OF TEXT:

\textheight 9.125in        % Height of text (including footnotes and
                         % figures, excluding running head and foot).
\textwidth 6.75in         % Width of text line.
                         % For two-column mode:
\columnsep 0.25in           %    Space between columns
\columnseprule 0pt       %    Width of rule between columns.
\renewcommand{\baselinestretch}{0.95}

% FLOATS: (a float is something like a figure or table)
%
%  FOR FLOATS ON A TEXT PAGE:
%
%    ONE-COLUMN MODE OR SINGLE-COLUMN FLOATS IN TWO-COLUMN MODE:
\floatsep 11pt plus 2pt minus 2pt        % Space between adjacent floats
                                         % moved to top or bottom of
                                         % text page.
\textfloatsep 0pt plus 2pt               % Space between main text and
                                         % floats at top or bottom of
                                         % page.
\intextsep 0pt plus 2pt                  % Space between in-text figures
                                         % and text.
\@maxsep 20pt                            % The maximum of \floatsep,
                                         % \textfloatsep and \intextsep
                                         % (minus the stretch and
                                         % shrink).
%    TWO-COLUMN FLOATS IN TWO-COLUMN MODE:
\dblfloatsep 11pt plus 2pt minus 2pt     % Same as \floatsep for
                                         % double-column figures in
                                         % two-column mode.
\dbltextfloatsep 0pt plus 2pt            % \textfloatsep for
                                         % double-column  floats.
\@dblmaxsep 20pt                         % The maximum of \dblfloatsep
                                         % and \dbltexfloatsep.

% \@startsection {NAME}{LEVEL}{INDENT}{BEFORESKIP}{AFTERSKIP}{STYLE}
%            optional * [ALTHEADING]{HEADING}
%    Generic command to start a section.
%    NAME       : e.g., 'subsection'
%    LEVEL      : a number, denoting depth of section -- i.e.,
%                 section=1, subsection = 2, etc.  A section number will
%                 be printed if and only if LEVEL < or = the value of
%                 the secnumdepth 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.
