-\section{Preamble}
-% ------------------------------------------------------------
-
-To use the \code{sankey} package, insert the following line in your preamble:
-
-\begin{lstlisting}[style=LaTeXsmall]
-\usepackage{sankey}
-\end{lstlisting}
-
-% ------------------------------------------------------------
-\section{The \texttt{sankeydiagram} environment}
-% ------------------------------------------------------------
-
-A \code{sankeydiagram} environment nested in a \code{tikzpicture}
-environment activates the sankey macros:
-
-\begin{lstlisting}[style=LaTeXsmall]
-\begin{tikzpicture}
- \begin{sankeydiagram}[... options ...]
- ... sankey macros ...
- \end{sankeydiagram}
-\end{tikzpicture}
-\end{lstlisting}
-
-% ------------------------------------------------------------
-\section{Sankey diagram options}
-% ------------------------------------------------------------
-
-The \code{sankey} package uses \code{pgfkeys} to define options via
-\emph{key=value} pairs.
-
-The options can be defined via the optional argument of the
-\code{sankeydiagram} environment:
-
-\begin{lstlisting}[style=LaTeXsmall]
-\begin{sankeydiagram}[debug=true]
- \sankeynode{name=a,quantity=1,angle=0,at={0,0}}
-\end{sankeydiagram}
-\end{lstlisting}
-
-The options can also be modified via the \code{\sankeyset} macro:
-
-\begin{lstlisting}[style=LaTeXsmall]
-\begin{sankeydiagram}
- \sankeyset{debug=true}
- \sankeynode{name=a,quantity=1,angle=0,at={0,0}}
-\end{sankeydiagram}
-\end{lstlisting}
-
-The options can be temporarily modified for a single macro:
-\begin{lstlisting}[style=LaTeXsmall]
-\begin{sankeydiagram}
- \sankeynode[debug=true]{name=a,quantity=1,angle=0,at={0,0}}
-\end{sankeydiagram}
-\end{lstlisting}
-% ------------------------------------------------------------
-\subsection{Keys to choose the scale}
-% ------------------------------------------------------------
-
-The scale or ratio of the Sankey diagram is the ratio between the %
-\code{ratio length} and the \code{ratio quantity}.
-
-\begin{sankeyoption}{ratio quantity}{\VAR{number}}{}{10}
- Quantity (in units of flow) to define ratio. The \VAR{number} can be
- any math expression.
-\end{sankeyoption}
-
-\begin{sankeyoption}{ratio length}{\VAR{distance}}{}{1cm}
- Distance (a graphical distance) to define scale.
-\end{sankeyoption}
-
-\begin{sankeyoption}{ratio}{\VAR{distance}/\VAR{number}}{}{1cm/10}
- Fix the ratio to \VAR{distance}/\VAR{number}.
-\end{sankeyoption}
-
-The initial ratio is 1\,cm/10 units.
-
-
-\textbf{Note:} the \code{sankey} package uses the \code{xfp} package to
-evaluate all math expressions that use quantities (in units of
-flow). You can therefore use quantities of a very large or very small
-order of magnitude. In contrast, for graphic distances, the sankey
-package uses the \code{pgfmath} package (all calculations must not
-exceed $\pm 16383.99999$).
-
-% ------------------------------------------------------------
-\subsection{Keys to define drawing parameters}
-% ------------------------------------------------------------
-
-\begin{sankeyoption}{minimum radius}{\VAR{distance}}{}{5mm}
- The minimum radius used by \code{\sankeyturn} and
- \code{\sankeydubins}.
-\end{sankeyoption}
-
-\begin{sankeyoption}{outin steps}{\VAR{integer}}{}{10}
- Number of steps used by the \code{\sankeyoutin} macro to simulate flow
- lanes with constant width.
-\end{sankeyoption}
-
-% ------------------------------------------------------------
-\subsection{Keys to choose drawing styles}
-% ------------------------------------------------------------
-
-\begin{sankeyoption}{fill/.style}{\VAR{style}}{}{{line width=0pt,fill=white}}
- This TikZ style is used to \emph{fill} all sankey paths.
-\end{sankeyoption}
-
-\begin{sankeyoption}{draw/.style}{\VAR{style}}{}{draw=black,line width=.4pt}
- This TikZ style is used to \emph{draw} all sankey paths.
-\end{sankeyoption}
-
-\begin{sankeyoption}{start style}{\VAR{style name}}{}{none}
- There are three predefined \emph{start} styles: \constant{none},
- \constant{simple}, \constant{arrow}.
-\end{sankeyoption}
-
-\begin{sankeyoption}{end style}{\VAR{style name}}{}{none}
- There are three predefined \emph{end} styles: \constant{none},
- \constant{simple}, \constant{arrow}.
-\end{sankeyoption}
-
-% ------------------------------------------------------------
-\subsection{Keys to define new \emph{start} and \emph{end} styles}
-% ------------------------------------------------------------
-
-\begin{sankeyoption}{new start style}{\{\VAR{name}\}\{\VAR{fill
- path}\}\{\VAR{draw path}\}}{}{}
- Define the new start style named \VAR{name} with its \VAR{fill
- path} and its \VAR{draw path}.
-\end{sankeyoption}
-
-\begin{sankeyoption}{new end style}{\{\VAR{name}\}\{\VAR{fill
- path}\}\{\VAR{draw path}\}}{}{}
- Define the new end style named \VAR{name} with its \VAR{fill
- path} and its \VAR{draw path}.
-\end{sankeyoption}
-
-\emph{Fill} and \emph{draw} paths are composed in a TikZ scope where
-the origin is the current Sankey node center (and its name is
-\code{\name}) and the coordinate system is rotated by its orientation.
-
-% ------------------------------------------------------------
-\subsection{The \emph{debug} key}
-% ------------------------------------------------------------
-
-\begin{sankeyoption}{debug}{\VAR{boolean}}{true}{false}
- To debug a sankey diagram.
-\end{sankeyoption}

-
-\begin{miniblock}
-\MACRO\code{\sankeynode}\OPTARG{\VAR{options}}\ARG{\VAR{node parameters}}
-
-The \code{\sankeynode} macro defines a Sankey node. The \VAR{options}
-can be any Sankey diagram keys. To define a Sankey node, you must
-provide a \emph{name}, a \emph{quantity}, an \emph{angle} and a
-\emph{position} as \VAR{node parameters}.
-
-\begin{sankeyoption}[/sankey/node parameters]{name}{\VAR{name}}{}{}
- The \VAR{name} of the new Sankey node (and the associated TikZ node).
-\end{sankeyoption}
-
-\begin{sankeyoption}[/sankey/node parameters]{quantity}{\VAR{quantity}}{}{}
- The quantity (in flow unit) of the new Sankey node. The \VAR{quantity}
- can be any math expression.
-\end{sankeyoption}
-
-\begin{sankeyoption}[/sankey/node parameters]{angle}{\VAR{angle}}{}{}
- The orientation of the flow (0 points to the right) of the new Sankey
- node.
-\end{sankeyoption}
-
-\begin{sankeyoption}[/sankey/node parameters]{at}{\VAR{at}}{}{}
- The position of the new Sankey node (a TikZ coordinate \emph{without}
- round brackets or parentheses).
-\end{sankeyoption}
-
-\begin{sankeyoption}[/sankey/node parameters]{anchor}{\VAR{anchor}}{center}{center}
- Specify the anchor of the Sankey node. Possible values are
- \constant{center}, \constant{left} or \constant{right}.
-\end{sankeyoption}
-
-\begin{sankeyoption}[/sankey/node parameters]{as}{\VAR{name}}{}{}
- Copy the \emph{name}, the \emph{quantity}, the \emph{angle} and the
- \emph{position} of the Sankey node named \VAR{name}.
-\end{sankeyoption}
-
-A Sankey node is also a Tikz node but with only three anchors:
-\code{left}, \code{center} and \code{right}.

-\newpage
-\subsection{Move nodes}
-% ------------------------------------------------------------
-
-The \code{\sankeyadvance} and \code{\sankeyturn} commands move a Sankey
-node (and fill/draw a portion of the Sankey flow). Then the previous
-position of the Sankey node is accessible via the \code{-old} suffix (if
-you move the \code{a} node, its previous position is the \code{a-old}
-node).

-\section{Miscellaneous}
-
-\subsection{The \texttt{debug} layer}
-
-The \code{debug} option key uses the \code{sankeydebug} layer to draw
-above the \code{main} TikZ layer (via \code{\pgfsetlayers}, the
-\code{sankey} package installs four layers: \code{background},
-\code{main}, \code{foreground}, \code{sankeydebug}).
-
-The four following styles define how to display debug informations:
-
-
-\begin{lstlisting}[style=LaTeXsmall]
-\sankeyset{
- % debug color used by all debug macros
- debug color/.style={/utils/exec={\colorlet{debug color}{#1}}},
- debug color=red!75!black,
- % debug line between left and right anchors
- debug line/.style={draw=debug color,|-|},
- % debug line between center and label
- debug normal/.style={draw=debug color},
- % debug node label
- debug label/.style={
- draw,
- font=\ttfamily\tiny,
- text=debug color,text opacity=1,
- inner sep=.1em,
- fill=white,fill opacity=1,
- rounded corners=.1em,
- },
-}
-\end{lstlisting}
-
-\subsection{The \texttt{dubins} TikZ library}
-
-The \code{sankey} package uses the \code{dubins} TikZ library (the
-\code{tikzlibrarydubins.code.tex} file) to compute Dubins paths. The
-documentation for this library does not yet exist.
-
-\subsection{How to duplicate a Sankey node}
-
-\MACRO\code{\sankeynodealias}\ARG{\VAR{origname}}\ARG{\VAR{clonename}}
-
-The \code{\sankeynodealias} macro clones the Sankey node named
-\VAR{origname} into the Sankey node named \VAR{clonename}.
-
-So, you can clone a Sankey node via two methods:
-
-\begin{lstlisting}[style=LaTeXsmall]
-\sankeynode{name=a,quantity=10,angle=0,at={0,0}}
-\sankeynode{as=a,name=b}
-\end{lstlisting}
-
-\begin{lstlisting}[style=LaTeXsmall]
-\sankeynode{name=a,quantity=10,angle=0,at={0,0}}
-\sankeynodealias{a}{b}
-\end{lstlisting}
-
-\subsection{How to define new start and end styles}
-
-Here are the definitions of the \code{arrow} styles:
-
-\begin{lstlisting}[style=LaTeXsmall]
-\sankeyset{
- % arrow style
- new start style={arrow}{
- (\name.left) -- ++(-10pt,0)
- -- ([xshift=-10pt/6]\name.center)
- -- ([xshift=-10pt]\name.right)
- -- (\name.right) -- cycle
- }{
- (\name.left) -- ++(-10pt,0)
- -- ([xshift=-10pt/6]\name.center)
- -- ([xshift=-10pt]\name.right)
- -- (\name.right)
- },
- new end style={arrow}{
- (\name.left) -- ([yshift=1mm]\name.left)
- -- ([xshift=10pt]\name.center)
- -- ([yshift=-1mm]\name.right) -- (\name.right) -- cycle
- }{
- (\name.left) -- ([yshift=1mm]\name.left)
- -- ([xshift=10pt]\name.center)
- -- ([yshift=-1mm]\name.right) -- (\name.right)
- },
-}
-\end{lstlisting}

+% The \texttt{sankey} package provides macros and environments to
+% build \emph{Sankey
+% diagrams}\footnote{\url{https://en.wikipedia.org/wiki/Sankey_diagram}},
+% i.e. \emph{flow diagrams} in which the width of the arrows is
+% proportional to the flow rate. The initial idea for the first
+% implementation came out from
+% \href{https://tex.stackexchange.com/q/40159/14500}{this question} on
+% \href{https://tex.stackexchange.com/}{TeX.StackExchange}.

+% \end{lstlisting}
+%

+% \code{sankey} package requires automatically the
+% \code{xparse}, \code{etoolbox}, \code{xfp} and

+% \code{decorations.markings} and
+% \code{dubins} (cf. \vref{sec:dubins}) TikZ libraries.\par}
+%
+%
+%^^A % ------------------------------------------------------------
+% \section{The \texttt{sankeydiagram} environment}
+%^^A % ------------------------------------------------------------
+%
+% \DescribeEnv{sankeydiagram} %
+% A \code{sankeydiagram} environment nested in a \code{tikzpicture}
+% environment activates the sankey macros:
+%
+% \begin{lstlisting}[style=LaTeXsmall]
+% \begin{tikzpicture}
+% \begin{sankeydiagram}[... options ...]
+% ... sankey macros ...
+% \end{sankeydiagram}
+% \end{tikzpicture}
+% \end{lstlisting}
+%
+%^^A % ------------------------------------------------------------
+% \section{Sankey diagram options}
+%^^A % ------------------------------------------------------------
+%
+% The \code{sankey} package uses \code{pgfkeys} to set options via
+% \emph{key=value} pairs with default path \texttt{/sankey} (and
+% \texttt{/sankey/node parameters} for Sankey node parameters).
+%
+% The options can be defined via the optional argument of the
+% \code{sankeydiagram} environment:
+%
+% \begin{lstlisting}[style=LaTeXsmall]
+% \begin{sankeydiagram}[debug=true]
+% \sankeynode{name=a,quantity=1,angle=0,at={0,0}}
+% \end{sankeydiagram}
+% \end{lstlisting}
+%
+% \DescribeMacro{\sankeyset} %
+% The options can also be modified via the \code{\sankeyset} macro:
+%
+% \begin{lstlisting}[style=LaTeXsmall]
+% \begin{sankeydiagram}
+% \sankeyset{debug=true}
+% \sankeynode{name=a,quantity=1,angle=0,at={0,0}}
+% \end{sankeydiagram}
+% \end{lstlisting}
+%
+% The options can be temporarily modified for a single macro:
+% \begin{lstlisting}[style=LaTeXsmall]
+% \begin{sankeydiagram}
+% \sankeynode[debug=true]{name=a,quantity=1,angle=0,at={0,0}}
+% \end{sankeydiagram}
+% \end{lstlisting}
+%
+% At the begining of each Sankey diagram, all options are initialized
+% with initial values then the \code{every diagram} style is applied.
+%
+% \begin{sankeyoption}{every diagram}{}{}{empty}
+% This style is installed at beginning of each Sankey diagram.
+% \end{sankeyoption}
+%
+% For instance, to use a ratio of 5mm/10 by default (instead of 1cm/10)
+% for all Sankey diagrams, add the following line:
+%
+% \begin{lstlisting}[style=LaTeXsmall]
+% \sankeyset{every diagram/.style={ratio=5mm/10}}
+% \end{lstlisting}
+%
+%^^A % ------------------------------------------------------------
+% \subsection{Keys to choose the scale}
+%^^A % ------------------------------------------------------------
+%
+% The scale or ratio of the Sankey diagram is the ratio between the %
+% \code{ratio length} and the \code{ratio quantity}.
+%
+% \begin{sankeyoption}{ratio quantity}{\VAR{number}}{}{10}
+% Quantity (in units of flow) to define ratio. The \VAR{number} can be
+% any math expression.
+% \end{sankeyoption}
+%
+% \begin{sankeyoption}{ratio length}{\VAR{distance}}{}{1cm}
+% Distance (a graphical distance) to define scale.
+% \end{sankeyoption}
+%
+% \begin{sankeyoption}{ratio}{\VAR{distance}/\VAR{number}}{}{1cm/10}
+% Fix the ratio to \VAR{distance}\texttt{/}\VAR{number}.
+% \end{sankeyoption}
+%
+% The initial ratio is 1\,cm/10 units.
+%
+%
+% \textbf{Note:} the \code{sankey} package uses the \code{xfp} package to
+% evaluate all math expressions that use quantities (in units of
+% flow). You can therefore use quantities of a very large or very small
+% order of magnitude. In contrast, for graphic distances, the sankey
+% package uses the \code{pgfmath} package (all calculations must not
+% exceed $\pm 16383.99999$).
+%
+%^^A % ------------------------------------------------------------
+% \subsection{Keys to define rotate offset}
+%^^A % ------------------------------------------------------------
+%
+% \begin{sankeyoption}{rotate}{\VAR{angle}}{}{0}
+%
+% The \code{rotate} key stores an offset angle applied to all Sankey
+% nodes. This is useful when using the \code{rotate} option within a
+% \code{tikzpicture} or a \code{scope}. This TikZ option is only
+% applied to coordinates and not to TikZ nodes (remember that Sankey
+% nodes are TikZ nodes). It's up to the author to keep the
+% \code{rotate} option of the \code{tikzpicture} and that of the
+% \code{sankeydiagram} synchronous.
+%
+% \end{sankeyoption}
+%
+%^^A % ------------------------------------------------------------
+% \subsection{Keys to define drawing parameters}
+%^^A % ------------------------------------------------------------
+%
+% \begin{sankeyoption}{minimum radius}{\VAR{distance}}{}{5mm}
+% The minimum radius used by \code{\sankeyturn} and
+% \code{\sankeydubins}.
+% \end{sankeyoption}
+%
+% \begin{sankeyoption}{outin steps}{\VAR{integer}}{}{10}
+% Number of steps used by the \code{\sankeyoutin} macro to simulate flow
+% lanes with constant width.
+% \end{sankeyoption}
+%
+%^^A % ------------------------------------------------------------
+% \subsection{Keys to choose drawing styles}
+%^^A % ------------------------------------------------------------
+%
+% \begin{sankeyoption}{fill/.style}{\VAR{style}}{}{{line width=0pt,fill=white}}
+% This TikZ style is used to \emph{fill} all sankey paths.
+% \end{sankeyoption}
+%
+% \begin{sankeyoption}{draw/.style}{\VAR{style}}{}{draw=black,line width=.4pt}
+% This TikZ style is used to \emph{draw} all sankey paths.
+% \end{sankeyoption}
+%
+% \begin{sankeyoption}{start style}{\VAR{style name}}{}{none}
+% There are three predefined \emph{start} styles: \constant{none},
+% \constant{simple}, \constant{arrow}.
+% \end{sankeyoption}
+%
+% \begin{sankeyoption}{end style}{\VAR{style name}}{}{none}
+% There are three predefined \emph{end} styles: \constant{none},
+% \constant{simple}, \constant{arrow}.
+% \end{sankeyoption}
+%
+%^^A % ------------------------------------------------------------
+% \subsection{Keys to define new \emph{start} and \emph{end} styles}
+%^^A % ------------------------------------------------------------
+%
+% \begin{sankeyoption}{new start style}{\{\VAR{name}\}\{\VAR{fill
+% path}\}\{\VAR{draw path}\}}{}{}
+% Define the new start style named \VAR{name} with its \VAR{fill
+% path} and its \VAR{draw path}.
+% \end{sankeyoption}
+%
+% \begin{sankeyoption}{new end style}{\{\VAR{name}\}\{\VAR{fill
+% path}\}\{\VAR{draw path}\}}{}{}
+% Define the new end style named \VAR{name} with its \VAR{fill
+% path} and its \VAR{draw path}.
+% \end{sankeyoption}
+%
+% \emph{Fill} and \emph{draw} paths are build in a TikZ scope where the
+% origin is the center of the current Sankey node (its name is accessible
+% via \code{\name}) and the coordinate system is rotated by its
+% orientation.
+%
+%^^A % ------------------------------------------------------------
+% \subsection{The \emph{debug} key}
+%^^A % ------------------------------------------------------------
+%
+% \begin{sankeyoption}{debug}{\VAR{boolean}}{true}{false}

+% \DescribeMacro{\sankeynode} %
+% The \code{\sankeynode} macro defines a Sankey node. The \VAR{options}
+% can be any Sankey diagram keys. To define a Sankey node, you must
+% provide a \emph{name}, a \emph{quantity} and an \emph{angle} as
+% \VAR{node parameters}.
+%
+% \begin{sankeyoption}[/sankey/node parameters]{name}{\VAR{name}}{}{}
+% The \VAR{name} of the new Sankey node (and the associated TikZ node).
+% \end{sankeyoption}
+%
+% \begin{sankeyoption}[/sankey/node parameters]{quantity}{\VAR{quantity}}{}{}
+% The quantity (in flow unit) of the new Sankey node. The \VAR{quantity}
+% can be any math expression.
+% \end{sankeyoption}
+%
+% \begin{sankeyoption}[/sankey/node parameters]{angle}{\VAR{angle}}{}{}

+% node.
+% \end{sankeyoption}
+%
+% \begin{sankeyoption}[/sankey/node parameters]{at}{\VAR{at}}{}{0,0}
+% The position of the new Sankey node (a TikZ coordinate \emph{without}
+% round brackets or parentheses).
+% \end{sankeyoption}
+%
+% \begin{sankeyoption}[/sankey/node parameters]{anchor}{\VAR{anchor}}{}{center}

+%
+% All the macros of this section move a Sankey node and fill/draw a

+% node is accessible via the \code{-old} suffix (i.e. if you move the
+% \code{a} node, its previous position is the \code{a-old} node).
+%
+% The starred version of each of these macros moves in the opposite
+% direction to their non-starred version.
+%
+% Except for the \code{\sankeyturn} macro, a negative value (distance or
+% angle) moves in the opposite direction (the \code{\sankeyturn} macro
+% is an exception: a negative angle turns right while a positive value
+% turns left).

+%
+% The options \code{debug} key uses the \code{sankeydebug} layer to draw
+% above the \code{main} TikZ layer (via \code{\pgfsetlayers}, the
+% \code{sankey} package installs four layers: \code{background},
+% \code{main}, \code{foreground}, \code{sankeydebug}).
+%
+% The four following styles define how to display debug information:
+%
+% \begin{lstlisting}[style=LaTeXsmall]

+% store a new value, the \emph{setter} macro name, the \emph{getter} macro name,
+% the \emph{cs name} used by the new field (including a \texttt{\#1}
+% parameter -- the \emph{key}) and the \emph{error message} (used by the getter
+% macro if the key is not defined).
+%
+% The \emph{setter} macro requires
+% two parameters: the key and the value.
+% The \emph{getter} macro requires
+% one parameter: the key.

+%
+%
+% A \code{sankey node} is defined as a TikZ node
+% with a particular \emph{shape}: its width is null and its
+% height matches the associated \emph{quantity}.
+% This shape requires only three anchors: \code{center}, \code{left}
+% and \code{right}.
+% These threee anchors are sufficient to use the
+% \code{sankey} package. But the \code{fit} library needs
+% anchors defined by rectangular node.
