%%% This set of macros is for making up transparencies in J.D. Callen's format.
%%% J.P. Wang and J.D.Callen, November 6, 1992
 
%%% To put a date or something else in the lower right corner, leaving 
%%% the top margin empty:
\def\ps@myheadings{\let\@mkboth\@gobbletwo
\def\@oddhead{}\def\@oddfoot{\hbox{}\small\hfil \@date, \hbox{} 
\rm p\hspace{0.4ex}\thepage}\def\@evenhead{}\def\@evenfoot{\hbox{} 
 \small\hfil \@date, \hbox{} \rm p\hspace{0.4ex} \thepage}}

%%% The titleline command sets up a line under the title, with fixed 
%%% spacing and thickness, extended over the whole text width: 
\newcommand\titleline{\bf \shortstack{\rule{\textwidth}{3pt}\\[1pt] 
  \rule{\textwidth}{1pt}}}  

%%% Using slanted bold fonts in transparency/viewgraph title (headline) 
% \font\slbf = cmbxsl10 scaled \magstep4  
\newfont{\slbf}{cmbxsl10 scaled \magstep1} % Smaller than \Slbf
\newfont{\Slbf}{cmbxsl10 scaled \magstep2} % Smaller than \SLbf
\newfont{\SLbf}{cmbxsl10 scaled \magstep3} % Smaller than \SLBf
\newfont{\SLBf}{cmbxsl10 scaled \magstep4} % Best for 12pt style title
\newfont{\SLBF}{cmbxsl10 scaled \magstep5} % Lager than \SLBf
\def\ttitle#1{\SLBf  \centering#1 \titleline} 

%%% The "bulletitems" environment is for the first-level, bullet items 
%%% that are to be un-indented:
\newenvironment{bulletitems}{\begin{list}{\Large\bf $\bullet $}{ 
 \addtolength{\leftmargin}{-2ex}} \Large\bf\protect\boldmath }{\end{list}} 

%%% For indented "Bulletitems" environment:
\newenvironment{Bulletitems}{\begin{itemize}\Large \bf 
 \protect\boldmath}{\end{itemize}} 

%%% The "items" environment is for the next level of items (nonbulletized): 
\newenvironment{items}{\begin{list}{}{\setlength{\leftmargin}{1.5ex}} 
  \large\bf\protect\boldmath}{\end{list}}  

%%% The "subitems" environment is for the usually lowest level of items: 
\newenvironment{subitems}{\begin{list}{}{\setlength{\leftmargin}{1.5ex}} 
 \normalsize\bf\protect\boldmath}{\end{list}}   

%%% The "subsubitems" environment is for the smallest print practicable: 
\newenvironment{subsubitems}{\begin{list}{}{\addtolength{\leftmargin}{-1ex}} 
 \small\bf\protect\boldmath}{\end{list}}
