+%
+% \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{}!

+% |\maketitle| informs \qcm{} that the title should be repeated on the form
+% and mask pages by defining |\@maketitle|.

+% \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.

+% redefined to the real value at the end of the |question| environment.
+%    \begin{macrocode}
