%   LaTeX slides macro
%   by Luis Cabral (luismbcabral@gmail.com)
%   (c) 2004-2008
%   For the past few years, I have been working on this sty file.  Ask me for the latest version.
%
%   This is a very "light" macro that does a decent job and does not take up a lot of memory.
%   Unlike beamer and other macros, it is compatible with PicTeX and other memory intensive macros.
%
\usepackage{ifthen}
\usepackage{color}
\usepackage{graphicx}
\usepackage[paperwidth=120mm,paperheight=90mm,pdftex,top=0in,bottom=0in,left=.35in,right=.35in]{geometry}
%
%   Set boolean variables.
%   You turn these on by entering (in your document)
%   \setboolean{handout}{true}, etc
%
\newboolean{author}
\newboolean{handout}
\newboolean{slidenumber}
%
%   Declare counters and indicators.
%   The ones you should worry about are: template and slidetype.
%   Both can be changed in the text.
%
\newcounter{template}
\newcounter{slidetype}
\newcounter{frame}
\newcounter{itemnumber}
%
%   Style declarations
%   Defines sanserif as default style.
%   You can change this or simply comment it out to get Times Roman instead.
%
\renewcommand{\familydefault}{\sfdefault}
\raggedright
%
%   Slide header and footer.
%   As a default, the footer only includes page number (if you turn slidenumber on).
%   In template 2, I redefine \slidefooter into something more complex.
%
\newcommand{\slideheader}[1]{\newpage\mbox{}\vspace*{-3.7ex}\par
    \hspace*{-6ex}\colorbox{titleshade}{\hspace*{2ex}\raisebox{5.0ex}{}\raisebox{-1ex}{}\color{title}
    {\Large\textbf{#1}}\hspace*{5in}}\vspace*{1ex}}
\newcommand{\slidefooter}{\vfill \ifthenelse{\boolean{slidenumber}}
    {\hspace*{-4.5ex}\raisebox{1.05ex}{\parbox{2ex}{\tiny\thepage}}}{}}
%
%   Item list and parameters.  You can play around with these,
%   For example, the bullet character is set at $\bullet$, but you can change it.
%   Major, minor, and minorminor refers to the three levels of lists I consider.
%
\newenvironment{list1}{\begin{list}{\majoritembullet}{\majorlistparameters}}{\end{list}}
\newenvironment{list2}{\vspace*{-.5ex}\begin{list}{\minoritembullet}{\minorlistparameters\small}}{\end{list}\normalsize}
\newenvironment{list3}{\vspace*{-.5ex}\begin{list}{\minorminoritembullet}{\minorlistparameters\small}}{\end{list}\normalsize}
\newcommand{\majoritembullet}{{\color{title}\raisebox{0.3ex}{\small$\bullet$}}}
\newcommand{\minoritembullet}{{\color{title}\raisebox{0ex}{$-$}}}
\newcommand{\minorminoritembullet}{{\color{title}\raisebox{0ex}{$\rightarrow$}}}
\newcommand{\majoritembulletdimmed}{{\color{gray}\raisebox{0.3ex}{\small$\bullet$}}}
\newcommand{\majorlistparameters}{\labelsep 1.5ex \leftmargin 3ex \labelwidth 2ex\itemsep .5ex \baselineskip 2.5ex}%

%   Slide animation.  This is the core of the sty file.
%   \repeatslide takes two "parameters": the number of repetitions, and the slide itself.
