% HOW TO USE THIS FILE % % % % % %
% 
% 0.	let "cheatsheet.tex" be the filename of the
% 		.tex-file that you want to turn into a cheatsheet
% 
% 1.	put this file into the same directory as cheatsheet.tex
% 
% 2.	remove the "\documentclass[]" from cheatsheet.tex
% 
% 3.	add "\input{densify.sty}" at the very top of cheatsheet.tex
% 
% 4.	make use of multicols by putting "\begin{multicols}{n}"
% 		before and "\end{multicols}" after the material that
% 		you want to have on your cheat sheet.
% 
% 		n: number of columns your cheat sheet will have.
% 
% 		ideally, your entire document will be between these lines,
% 		(the "\begin{multicols}{n}" right after "\begin{document}"
% 		and "\end{multicols}" right before "\end{document}")
% 
% 5.	enjoy your densified cheat sheet!

% MAIN STUFF THAT MAKES THIS WORK

% (if any of these \usepackage is already in
% your cheatsheet.tex then remove it from there,
% since it'll be included from here anyway)
