%%%%%

% This just brings together some (possibly ugly) hacks that I use when writing math. Likely, you do not want to use this except when building around this package (like I did), or already have similar shortcuts

%Proper Degree command
\def\mkessler@mathfixes@degree{^\circ}
\AtBeginDocument{\def\degree{\mkessler@mathfixes@degree}}

% Always put limits under \limit
\let\oldlim\lim\def\lim{\oldlim\limits}

% Print equal sign under subset by default to not confuse people
% (I still write \subset, because this enables me remove this renewcommand and have the default \subset command evaluated instead
\renewcommand\subset\subseteq
\renewcommand\supset\supseteq


%%Renew phi and epsilon to their proper versions, make the old ones available as 
% uglyphi and uglyepsilon

\let\mkessler@mathfixes@oldphi\phi
\renewcommand\phi\varphi
\newcommand\uglyphi{\mkessler@mathfixes@oldphi}

\let\mkessler@mathfixes@oldepsilon\epsilon
\renewcommand\epsilon\varepsilon
\newcommand\uglyepsilon{\mkessler@mathfixes@oldepsilon}
