% quiz2socrative.sty -- preparing questions for socrative quizzes
% by Paolo Lella &lt;paolo.lella@polimi.it&gt;
%
% quiz2socrative.sty is a LaTeX package for preparing
% multiple choice, true/false and short answer questions.
% The main purpouse is to offer a tool to easily insert rather complicated 
% mathematical stuff in socrative quizzes (see https://socrative.com).
%
% This is quiz2socrative version 1.0, October 2019.
