+% \section{Introduction}
+%
+% The file \file{\filename}\footnote{The file described in this
+% section has version number \fileversion\ and was last revised on
+% \filedate.}, provides a command |\lettrine| which requires two
+% mandatory arguments, and an optional one.
+%
+% Adding |\usepackage{lettrine}| in the preamble of a document
+% defines the command |\lettrine|, the simplest use of which is
+% |\lettrine{|\emph{$<$letter$>$}|}{|\emph{$<$text$>$}|}|.
+% It produces a dropped capital \emph{$<$letter$>$} (2 lines high),
+% followed by \emph{$<$text$>$} typeset in small caps, and the rest
+% of the paragraph is wrapped around the dropped capital.
+%
+% Various parameters are provided to control the size and layout
+% of the dropped capital and match the requirements described
+% in the books
+% \begin{itemize}
+% \item ``Lexique des r\`egles typographiques en usage \`a
+% l'Imprimerie nationale'' troisi\`eme \'edition (1994),
+% ISBN-2-11-081075-0,
+% \item ``Mise en page et impression'' Yves~\textsc{Perrousseaux},
+% ISBN-2-911220-01-3.
+% \end{itemize}
+% The parameters can be set using David Carlisle's
+% \texttt{keyval.sty} syntax:
+% \begin{itemize}
+% \item |lines=|\emph{$<$integer$>$} sets how many lines the
+% dropped capital will occupy (default=2);
+% \item |lhang=|\emph{$<$decimal$>$} ($0\le|lhang|\le1$) sets
+% how much of the dropped capital's width should hang into
+% the margin (default=0);
+% \item |loversize=|\emph{$<$decimal$>$} ($-1<|loversize|\le1$)
+% enlarges the dropped capital's height: with
+% |loversize=0.1| its height is enlarged by 10\% so that
+% it raises above the top paragraph's line (default=0);
+% \item |lraise=|\emph{$<$decimal$>$} does not affect the dropped
+% capital's height, but moves it up (if positive),
+% down (if negative); useful with capitals like |J| or |Q|
+% which have a positive depth, (default=0);
+% \item |findent=|\emph{$<$dimen$>$} (positive or negative)
+% controls the horizontal gap between the dropped capital
+% and the indented block of text (default=0pt);
+% \item |nindent=|\emph{$<$dimen$>$} shifts all indented lines,
+% starting from the second one, horizontally by
+% \emph{$<$dimen$>$} (this shift is relative to the first
+% line, default=0.5em);
+% \item |slope=|\emph{$<$dimen$>$} can be used with dropped
+% capitals like |A| or |V| to add \emph{$<$dimen$>$}
+% (positive or negative) to the indentation of each line
+% starting from the third one (no effect if |lines=2|,
+% default=0pt);
+% \item |ante=|\emph{$<$text$>$} can be used to typeset
+% \emph{$<$text$>$} \emph{before} the dropped capital
+% (typical use is for French guillemets starting
+% the paragraph).
+%
+% \changes{lettrine-1.6}{2004/05/22}{Add a flag to switch to
+% images in eps or pdf format. Suggested by Bill Jetzer.}
+%
+% \item |image=|\emph{$<$true$>$} (new to version 1.6) will force
+% |\lettrine| to replace the letter normally used as
+% dropped capital by an image in eps format (latex) or
+% in pdf, jpg, etc. format (pdflatex); this needs the
+% |graphicx| package to be loaded in the preamble of course.
+% |\lettrine[image=true]{A}{n exemple}| or just
+% |\lettrine[image]{A}{n exemple}| will load |A.eps|
+% or |A.pdf| instead of letter~A. This was suggested
+% by Bill Jetzer. Redefining \verb+\LettrineFont+ as
+% \verb+\LettrineFontEPS+ still works for compatibility
+% but is deprecated.
+% \end{itemize}
+%
+% Example: |\lettrine[lines=4, lraise=0.1, nindent=0em, |%
+% |slope=-.5em]%|\\
+% \mbox{}\phantom{\tt Example: lettrine}%
+% |{V}{oici} un exemple |\dots
+%
+% Coloured lettrines are possible in conjonction with package
+% \file{color}, examples: |\lettrine{\textcolor{red}{A}}{n} example|
+% \quad or\\ |\lettrine{\textcolor[gray]{0.5}{A}}{nother} one| \\
+% see package \file{color} for the syntax of colour commands.
+% Another possibility to colour lettrines globally is described
+% below, see |\LettrineFontHook|.
+%
+% Once \file{lettrine.sty} will be installed (run \texttt{latex}
+% on \file{lettrine.ins} to extract it), compile and print
+% \file{demo.tex} to see the possible usage of these parameters.
+%
+% The default settings can be customized either in a config file
+% \file{lettrine.cfg} (for a global usage), or on a per document
+% basis, in the preamble of each document. The following list
+% shows the syntax to set them and their default values:
+% \begin{itemize}
+% \item |\setcounter{DefaultLines}{2}|,
+% \item |\renewcommand{\DefaultLoversize}{0}|,
+% \item |\renewcommand{\DefaultLraise}{0}|,
+% \item |\renewcommand{\DefaultLhang}{0}|,
+% \item |\LettrineImagefalse|,
+% \item |\setlength{\DefaultFindent}{0pt}|,
+% \item |\setlength{\DefaultNindent}{0.5em}|,
+% \item |\setlength{\DefaultSlope}{0pt}|.
+% \end{itemize}
+%
+% Instead of giving optional parameters to the |\lettrine| command,
+% it is possible, from version 1.5, to set them on a per character
+% basis in a second config file (suggested by Pascal Kockaert):
+% |\renewcommand{\DefaultOptionsFile}{|\textit{filename}|}|
+% in the preamble (or anywhere in the document) will
+% force each call to |\lettrine| to read the file \textit{filename}.
+% See examples of such config files in the subdirectory
+% \file{contrib}.
+%
+% The dimensional parameters |findent|, |nindent| and |slope|,
+% can be set in \textit{filename} relative to |\LettrineWidth|
+% if needed.
+% |\LettrineWidth| should be used \emph{only} in the config file
+% \textit{filename}, its value is non-null only if \textit{filename}
+% is read!
+% The settings read from this file will be overridden by the
+% optional arguments eventually given to |\lettrine|.
+%
+% |\LettrineTextFont| sets the font used for the second argument
+% of |\lettrine|, its default definition is
+% |\newcommand{\LettrineTextFont}{\scshape}| (second argument in
+% small caps, this can be changed using |\renewcommand|).
+%
+% |\LettrineFont| sets the font used for the dropped capital,
+% usually the current font in a (large) size, computed
+% automatically from the number of lines it will fill:
+% the font size is computed so that, a \emph{standard} dropped
+% capital (say X, not \`A) when sitting on its baseline, gets
+% its top aligned with the top of the following text (provided
+% $|loversize|=0$ and $|lines|\ge 2$). When $|lines|=1$,
+% size is computed as if |lines| was~2.\\
+% A hook |\LettrineFontHook| is provided to change the font
+% used for the dropped capital, syntax follows \LaTeX{}'s
+% low-level font interface (see \LaTeX{} Companion, p.187--192),
+% the |\selectfont| command is issued by |\LettrineFont|:\\
+% |\renewcommand{\LettrineFontHook}{\fontfamily{ppl}|\ignorespaces
+% |\fontseries{bx}}%|\\
+% | \fontshape{sl}}|,\\
+% selects Palatino bold expanded slanted for the dropped capital.\\
+% |\LettrineFontHook| can also be used to change the colour of
+% all lettrines in a (part of) document:
+% |\renewcommand{\LettrineFontHook}{\color[gray]{0.5}}| \\
+% will colour the lettrines following this command in grey.
+%
+% \changes{lettrine-1.3}{2002/08/23}{Correct the documentation to
+% mention the cm-super fonts and the type1ec package by
+% Vladimir Volovich.}
+%
+% \vspace{\baselineskip}
+% \textbf{Important notice:}
+% the sizing works fine with \emph{fully scalable} fonts (like the
+% standard PostScript fonts), but might not work well with CM/EC
+% fonts which have two limitations: only a limited number of sizes
+% is available by default (precise adjustments are impossible),
+% and the largest size (25pt or 35pt) is often too small.
+% The CM fonts are now available in PostScript type1 format for
+% free (courtesy of BlueSky/Y\&Y), to make them fully scalable,
+% it is mandatory to add |\usepackage{type1cm}| in the preamble
+% of your document.
+% The EC fonts are also available in type1 format for free
+% (thanks to Vladimir Volovich, they are called cm-super), and
+% adding |\usepackage{type1ec}|%
+% \footnote{This package, available on CTAN, was first released
+% on 2002/07/30.}
+% in the preamble will make them fully scalable too.
+% So, if you want \file{lettrine.sty} to work properly with CM
+% or EC fonts, you will need \emph{PostScript versions} of these
+% fonts \emph{and} one of the packages |type1cm.sty| or
+% |type1ec.sty|.
+%
+% The newly released LM fonts, which should replace both CM and
+% EC fonts sooner or later, are fully scalable, so, if you have
+% them installed, you should use them instead of CM or EC fonts.
+% |\usepackage{lmodern}| is the command to switch them on (add
+% |\usepackage[T1]{fontenc}| when composing in one of the western
+% languages other than English in order to get proper hyphenation).
+%
+% You can also consider using one of the standard PostScript fonts
+% (Palatino, Times, Utopia\dots), they are fully scalable too!
+%
+% \vspace{\baselineskip}
+% \textbf{Known problems:}
+% \begin{itemize}
+% \item nothing is done to prevent page-breaking in a paragraph
+% starting with a dropped capital; when it happens to hang
+% into the footer, page-breaking has to be done manually;
+% \item |\lettrine| works within `quote' `quotation', `abstract'
+% environments but does not work within `center' environments
+% (except with option \texttt{[lines=1]});
+% \item |\lettrine| does not work within lists;
+% \item if a \emph{list} has to be included in a paragraph starting
+% with a `lettrine', it is necessary to add the command
+% |\parshape=0| just after the end of the list (starting a new
+% paragraph just before or just after the list works too).
+% Remember that `quote', `quotation', `abstract' environments
+% are implemented as \emph{lists} in \LaTeX{}.

+% (and |\L@oversize|, see |\LettrineFont|).
+% \begin{macrocode}
+ \setlength{\L@lraise}{-\L@raise\L@first}%
+ \addtolength{\L@first}{\L@lraise}%
+ \addtolength{\L@first}{\ht\L@lbox}%
+ \addtolength{\L@lraise}{-\theL@lines\@tempdima}%

+ \fi
+ \par
+ \ifdim\L@first>0.2\p@\vskip\L@first\fi
+% \end{macrocode}
+% Again, we (mis)use the length |\L@first| to compute the width of
+% the text eventually coming before the dropped capital. It is
+% reset later on to hold the first line's length.
+% \begin{macrocode}
+ \setlength{\L@Pindent}{\wd\L@lbox}%
+ \addtolength{\L@Pindent}{-\L@hang\wd\L@lbox}%
+ \settowidth{\L@first}{\L@ante}%
+ \addtolength{\L@Pindent}{\L@first}%
+ \addtolength{\L@Pindent}{\L@Findent}%
+ \setlength{\L@first}{\linewidth}%
+ \addtolength{\L@first}{-\L@Pindent}%
+% \end{macrocode}
+% Now let's compute |\L@Nindent| and |\L@next| for the next lines.
+% \begin{macrocode}
+ \addtolength{\L@Nindent}{\L@Pindent}%
+ \setlength{\L@next}{\linewidth}%
+ \addtolength{\L@next}{-\L@Nindent}%
+% \end{macrocode}

+% \changes{lettrine-1.1}{1999/08/18}{Add \cs{rightmargin} to
+% \cs{L@Pindent} for \cs{Lettrine} to work properly in quote,
+% quotation, abstract environments\dots{} but do not change
+% \cs{linewidth} which is set by these environments.}
+%
+% \changes{lettrine-1.4}{2002/10/26}{\cs{lettrine} still didn't
+% work properly in quote, quotation, abstract environments,
+% pointed out by Matthias C. Schmidt. \cs{rightmargin} was added
+% too early to \cs{L@Nindent}, thus making \cs{\L@next} too short
+% by \cs{rightmargin}.}
+%
+% This is for quotation, quote, abstract\dots{} environments:
+% |\linewidth| is set by these environments, all we have to do
+% is to shift our text left by |\rightmargin| (amount of space
+% locally added to |\leftmargin| in these environments).
+% \begin{macrocode}
+ \addtolength{\L@Pindent}{\rightmargin}%
+ \addtolength{\L@Nindent}{\rightmargin}%
+% \end{macrocode}
+% Now, set up the shape of the new paragraph (designed by
+% |\parshape|).
+% \begin{macrocode}
+ \addtocounter{L@lines}{1}%
+ \def\L@parshape{\c@L@lines \the\L@Pindent \the\L@first}%
+ \@tempcnta=\tw@
+ \@whilenum \@tempcnta<\c@L@lines\do{%
+ \edef\L@parshape{\L@parshape \the\L@Nindent \the\L@next}%
+ \addtolength{\L@Nindent}{\L@slope}%
+ \addtolength{\L@next}{-\L@slope}%
+ \advance\@tempcnta\@ne}%
+ \edef\L@parshape{\L@parshape \rightmargin \the\linewidth}%
+ \noindent\leavevmode
+ \parshape=\L@parshape
+% \end{macrocode}
+% Write the dropped capital into the left margin, and wrap
+% the rest of paragraph around it.
+% \begin{macrocode}
+ $\smash{\llap{\mbox{\L@ante}\raisebox{\L@lraise}{\usebox{\L@lbox}}%
+ \hskip \the\L@Findent}}$%
+ \usebox{\L@tbox}}
