+(@emph{QCM} is the French acronym for this style of test).  A special
+environment allows you to define questions and possible answers.  You can
+specify which answers are correct and which are not.  QCM not only formats the
+questions for you, but also generates a form (a grid that your students will
+have to fill in), and a mask (the same grid, only with correct answers
+properly checked in).  You can then print the mask on a slide and correct the
+questionnaires more easily by superimposing the mask on top of students forms.
+QCM can also typeset exam corrections automatically, and comes with support
+for AUC-TeX.")
