% DESCRIPTION:
|
|
%
|
|
% This file contains macros for sections, headings, tables of contents,
|
|
% and lists of slides, for slides. It can probably be used with your
|
|
% favorite LaTeX slide package (e.g., seminar.sty).
|
|
% However:
|
|
%% If the counter used to keep track of slides is not slide ,
|
|
%% then change the following line:
|
|
\def\@SCTR{\theslide}
|
|
%%
|
|
% ACKNOWLEDGEMENTS:
|
|
%
|
|
% The idea comes from Young U. Ryu's lslides.sty.
|
|
%
|
|
% USAGE:
|
|
%
|
|
% \slideheading[#1]{#2}
|
|
% * Analogous to \section.
|
|
% * [#1] is optional; \slideheading{#1} is same as \slideheading[#1]{#2}.
|
|
% * Advances slidesection counter.
|
|
% * Sets \theslideheading to #1; can be used, e.g., in headers and footers.
|
|
% * Adds #1 to slide contents file.
|
|
% * If #2 is non-empty, invokes \makeslideheading{#2} to make a heading.
|
|
% Default definition of \makeslideheading is
|
|
% \begin{center}\large\bf #2 \end{center}
|
|
% but you can redefine this to suit your tastes.
|
|
%
|
|
% \slidesubheading[#1]{#2}
|
|
% * Analogous to \subsection.
|
|
% * Like \slideheading, but add "sub" to all the names.
|
|
%
|
|
% \slideheading and \slidesubheading are meant to be used at most once in
|
|
% a slide, but this is not a binding restriction.
|
|
%
|
|
% You may want to define abbreviated forms. E.g.,
|
|
% \newcommand{heading}{\slideheading}
|
|
% \newcommand{subheading}{\slidesubheading}
|
|
%
|
|
% \listofslides
|
|
% * Analogous to \listoftables.
|
|
%
|
|
% \slidecontents
|
|
% * Analogous to \tableofcontents
|
|
%
|
|
% \Slidecontents
|
|
% * List \slidecontents, but puts some check marks and stuff to
|
|
% indicate what you have covered so far and what is coming up.
|
|
% Meant to be used in the middle of a presentation.
|
|
%
|
|
% To change fonts and otherwise customize what you get from \listofslides,
|
|
% \slidecontents, and \Slidecontents, you have to hack at the definitions
|
|
% of these macros.
|
|
%
|
|
% BUGS:
|
|
%
|
|
% These macros have not been tested very much.
|
|

|

% IMPLEMENTATION:

% but it sets the flae \los@flag to 1, and then we add a few commands
|

% to \enddocument that open \filename.los if \los@flag=1.
