% \begin{abstract}
% \qcm{} is a package for making multiple choices questionnaires
% (``\textsc{QCM}'' is the corresponding French acronym) under \LaTeXe. 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.\par
% The \qcm{} package is \packagecopyright{}, and distributed under the terms
% of the LPPL license.
% \end{abstract}
%
% \section{Using \qcm{} (attention users of version 1)}
% As of version 2.0, \qcm{} comes both in style and class form. The style
% provides all the basic features: making questions, generating the form and
% the mask\ldots You can use it with any class you want, which is useful when
% you want to incorporate multiple choice questions in a larger document (a
% full exam for instance).\par
% If you want to make simple multiple choice questionnaires, with just a list
% of questions, you can alternately use the class which provides some basic
% formatting on top of the style itself.
%
% \section{The \qcm{} Style}
% First of all, please note that \qcm{} requires the packages \texttt{ifthen},
% \texttt{calc} and \texttt{tabularx}. As of version 2.1, the
% \texttt{verbatim} package is also required. You don't have to require these
% packages explicitly though. As long as \LaTeXe{} is able to locate them,
% they will be used automatically.\par
% In order to use the \qcm{} style, say |\usepackage[|\meta{options}|]{qcm}|
% in the preamble of your document. The available options are described along
% the text, where appropriate.
%
% \subsection{Creating Questions}
% Here's a simple example demonstrating how to produce a new question:
% \begin{verbatim}
% \begin{question}{What is the color of Henri the Fourth's white horse?}
%   \false black,
%   \true white,
%   \false yellow,
%   \false red.
% \end{question}
% \begin{correction}
% The correct answer is white, because it's in the question.
% \end{correction}
% \end{verbatim}
%
% \subsubsection{The \texttt{question} environment}
% \DescribeEnv{question}
% The |question| environment allows you to insert questions into your
% document. It takes one mandatory argument which specifies the actual
% question's text. The question will be displayed in a frame box, the size of
% the line.\par
% \DescribeMacro{\true}\DescribeMacro{\false}
% The proposed answers are displayed below the question in a list fashion (the
% |question| environment is a list-based one). Instead of using |\item|
% however, use either |\true| or |\false| to insert a possible answer.\par
%
% \subsubsection{Question Numbers}
% The |question| environment is associated with a \LaTeX{} counter named
% |question|. This counter stores the number of the next (or current)
% question. It is initialized to 1, and automatically incremented at the end
% of |question| environments. You might want to use it to format question
% titles. For instance, you could decide that each question belongs to a
% subsection in the |article| class, and use something like this before each
% question: |\subsection*{Question \thequestion}|
%
% \subsection{The Form and the Mask}
% Based on the questions appearing in your document, \qcm{} has the ability to
% generate 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).
% This can make the correction process easier.\par
% \DescribeMacro{\makeform}
% \DescribeMacro{\makemask}
% To generate a form and a mask, use the macros |\makeform| and |\makemask|.
% \qcm{} uses two auxiliary files to build them. These files have respectively
% an extension of \texttt{frm} and \texttt{msk}. If you use these macros, you
% will need two passes of \LaTeXe{} in order to get a correctly formatted
% document.\par
%
% \subsection{Typesetting corrections}
% \DescribeEnv{correction}
% As of version 2.1, \qcm{} comes with a ``correction'' mode which allows you
% to automatically typeset and distribute corrections to your students. These
% corrections are slightly modified versions of your questionnaire: each
% possible answer is prefixed with a small symbol (a visual clue) indicating
% whether the answer was correct or wrong. In addition, you can typeset
% explanations below each question.\par
% To activate the correction mode, use the |correction| option. It is off by
% default.\par
% To typeset explanations below the questions, use the |correction|
% environment (no argument). The contents of this environment is displayed
% only in |correction| mode. In normal mode, it is simply discarded.\par
% In addition, note that \qcm{} cancels the actions performed by |\makeform|
% and |\makemask| in |correction| mode. This is to avoid further edition of
% the source when typesetting a correction.
%
% \subsection{Important Note}
% Currently, \qcm{} requires that you provide a constant number of proposed
% answers across all questions in your \textsc{QCM}. This is something natural
% when you want to build forms, but this might me too restrictive otherwise,
% I'm not sure, so it is possible that this restriction will be removed in
% future versions.\par
% Currently, there is a built-in mechanism for checking that the number of
% proposed answers remains constant: when \qcm{} encounters the first
% occurrence of the |question| environment, it remembers the number of proposed
% answers from there. Afterwards, any noticed difference in subsequent
% occurrences will generate an error. As a consequence, you never have to tell
% \qcm{} explicitly what that number is.
%
% \subsection{Customizing the \qcm{} style}
% \subsubsection{The question environment}
% \DescribeMacro{\questionspace}
% |\questionspace| is the amount of extra vertical space to put under the
% question, before the list of proposed answers. This is a \LaTeX{} length
% that defaults to \texttt{0pt}.\par
% \DescribeMacro{\answerstitlefont}
% Before the list of possible answers, a short title is displayed (for
% English, it reads ``Possible answers:''). The |\answerstitlefont| macro
% takes one mandatory argument which redefines the font to use for the answers
% title. By default, |\bfseries| is used.\par
% \DescribeMacro{\answernumberfont}
% Each proposed answer in the list is numbered automatically (and
% alphabetically). The |\answernumberfont| macro takes one mandatory argument
% which redefines the font to use for displaying the answer number. By
% default, |\bfseries| is used.\par
%
% \subsubsection{The Form and the Mask}
% \DescribeMacro{\headerfont}
% The |\headerfont| macro takes one mandatory argument which redefines
% the font to use for the headers (first line and first column) of the form
% and mask arrays. By default, |\bfseries| is used.\par
% \DescribeMacro{\X}
% In the mask, correct answers are checked in by filling the corresponding
% cell with an ``X'' character. If you want to change this, call the |\X|
% macro with one (mandatory) argument.
%
% \subsubsection{The correction}
% \DescribeMacro{\truesymbol}
% \DescribeMacro{\falsesymbol}
% In correction mode, labels in front of answers are modified to give a visual
% clue about whether the answer was correct or wrong. By default, a cross and
% a small arrow are used. You can change these symbols by using the
% |\truesymbol| and |\falsesymbol| macros. For instance, you could give a
% fancier look to your correction by using the |pifont| package and issuing:
% \begin{verbatim}
% \truesymbol{\ding{'063}~}
% \truesymbol{\ding{'067}~}
% \end{verbatim}
% \DescribeMacro{\correctionstyle}
% The appearance of the contents of the |correction| environment can be
% adjusted by using the |\correctionstyle| macro. By default, |\itshape| is
% used.
% \subsubsection{Internationalization}
% \DescribeEnv{english}
% \DescribeEnv{french, francais}
% \qcm{} currently supports English, and French. You can select the language
% you want to use by using the corresponding option. The \texttt{french} and
% \texttt{francais} options are synonyms. If you want a finer grain on the
% language-dependent parts of \qcm, the following macros are provided.\par
% \DescribeMacro{\answerstitle}
% This macro takes one mandatory argument which lets you redefine the
% answers'titles. For English, the answers title defaults to
% ``Possible answers:''.\par
%
%
% \section{The \qcm{} Class}
% The \qcm{} class provides a wrapper around the style to allow you to format
% simple multiple choice questionnaires, with just a list of questions.\par
% In order to use the \qcm{} class, say
% |\documentclass[|\meta{options}|]{qcm}| at the beginning of your document.
% The available options are described along the text, where appropriate. Note
% that the underlying \qcm{} style is loaded automatically.
%
% \subsection{Standard Class Features}
%
% \subsection{Page Size and layout}
% \DescribeEnv{a4paper}
% \DescribeEnv{a5paper}
% \DescribeEnv{b4paper}
% \DescribeEnv{letterpaper}
% \DescribeEnv{legalpaper}
% \DescribeEnv{executivepaper}
% \DescribeEnv{landscape}
% The \texttt{a4}, \texttt{a5}, \texttt{b4}, \texttt{letter}, \texttt{legal}
% and \texttt{executive}  ``paper'' options allow you to select the type of
% page format you want. By default, \texttt{letterpaper} is used. The
% \texttt{landscape} options switches the horizontal and vertical settings.
% I'm not sure why I propose this option. Nobody wants to write a \textsc{QCM}
% in landscape mode, right?\par
%
% \DescribeEnv{oneside}
% \DescribeEnv{twoside}
% \qcm{} also supports the standard \texttt{oneside} and \texttt{twoside}
% class options. By default, \texttt{oneside} is used. In \texttt{twoside}
% mode, odd and even pages have a different geometry and headings layout.
%
% \subsection{Font Size}
% \DescribeEnv{10pt}
% \DescribeEnv{11pt}
% \DescribeEnv{12pt}
% The \texttt{10pt}, \texttt{11pt} and \texttt{12pt} options let you choose
% the size of the default font you want to use. By default, \texttt{10pt} is
% used.
%
% \subsection{Output Mode}
% \DescribeEnv{final}
% \DescribeEnv{draft}
% In \texttt{draft} mode, a black rule will be drawn at the end of overfull
% lines (as done by standard classes).
%
% \subsection{Page styles}
% \qcm{} supports the standard \LaTeX{} page style mechanism. Available styles
% are \texttt{empty}, \texttt{plain}, \texttt{headings} and
% \texttt{myheadings}. These styles have their usual meaning, except that
% there are no sectioning commands in the \qcm{} class. By default, the page
% style is \texttt{plain}. Also, note that the form and the mask have an empty
% page style, whatever the setting for the rest of the document.
%
% \subsection{Title}
% \DescribeMacro{\title}
% The |\title| macro takes one mandatory argument which defines a title for
% your questionnaire (repeated on the form and the mask). It can be used in
% the document's preamble only. The title will be centered on the page.\par
% \DescribeMacro{\titlefont}
% The |\titlefont| macro takes one mandatory argument which redefines the
% font to use for the title. By default, |\LARGE\bfseries| is used.\par
% \DescribeMacro{\titlespace}
% |\titlespace| is the amount of extra vertical space to put after the title.
% This is a \LaTeX{} length that defaults to \texttt{20pt}.\par
% \DescribeMacro{\maketitle}
% If you have defined a title, make it appear by calling |\maketitle| after
% the beginning of your document. If you call |\maketitle| without having
% defined a title, an error will be generated.
%
% \subsection{Modifications to the question environment}
% The \qcm{} class modifies the |question| environment so as to display a
% title before each question (something that you would probably do with a
% sectioning command in other classes). This title is displayed in a frame
% box, the size of a quarter of the line. For English, the default reads
% ``Question n.\meta{X}:''.\par
%
% \subsection{Modifications to \cs{makeform} and \cs{makemask}}
% The \qcm{} class modifies |\makeform| and |\makemask| along the following
% lines: each grid is printed on a page of its own, and the document's title
% is repeated on top of each. Also, the page style is set to |empty|.
%
% \subsection{Customizing the \qcm{} class}
% \subsubsection{The question titles}
% \DescribeMacro{\questiontitlefont}
% The |\questiontitlefont| macro takes one mandatory argument which redefines
% the font to use for each question title. By default, |\bfseries| is
% used.\par
% \DescribeMacro{\questiontitlespace}
% |\questiontitlespace| is the amount of extra vertical space to put after the
% question title (and before the questions' text). This is a \LaTeX{} length
% that defaults to \texttt{5pt}.\par
% \DescribeMacro{\questionsepspace}
% In addition, questions are separated from each other by some vertical space.
% |\questionsepspace| is the amount of extra vertical space to put between
% each question block. This is a \LaTeX{} length that defaults to
% \texttt{20pt}.
%
% \subsubsection{Internationalization}
% \DescribeEnv{english}
% \DescribeEnv{french, francais}
% \qcm{} currently supports English, and French. You can select the language
% you want to use by using the corresponding option. The \texttt{french} and
% \texttt{francais} options are synonyms. If you want a finer grain on the
% language-dependent parts of \qcm, the following macros are provided.\par
% \DescribeMacro{\questiontitle}
% This macro takes one mandatory argument which lets you redefine the
% questions'titles. For English, the question title defaults to
% ``|Question N.\thequestion:|''.\par
%
%
% \section{\auctex{} support}
% \auctex{} is a powerful major mode for editing \TeX{} documents in
% \textsf{Emacs} or \textsf{XEmacs}. In particular, it provides automatic
% completion of macro names once they are known. \qcm{} supports \auctex{}
% by providing a style file named \texttt{qcm.el} which contains \auctex{}
% definitions for the relevant macros. This file should be installed to a
% location where \auctex{} can find it (usually in a subdirectory of your
% \LaTeX{} styles directory). Please refer to the \auctex{} documentation for
% more information on this.\par
% For people already knowing \auctex: note that the \auctex{} command
% \texttt{LaTeX-insert-item} (usually bound to \texttt{M-Ret}) inserts
% |\false| by default in a \textsc{QCM}, since it replaces |\item|. If you
% want to insert a |\true|, use a prefix.
%
% \StopEventually{\par Well, I think that's it. Enjoy using \qcm{}!

% \subsection{The Form and Mask}
% The qcm{} style |\makeform| and |\makemask| macros are saved and wrapped
% into new ones that first repeat the document's title on a new page. The page
% style is also set to |empty|.\par
% For a reason I don't recall anymore, |\addtocontents| fails to write
% anything in the auxiliary files when nothing has been written on the page
% yet. To cope with this problem, we restate the title first.
