% \begin{abstract}
% The \textsf{mahjong} package provides a \LaTeXe{} and \LaTeX~3 interface for typesetting mahjong tiles using an extended version of MPSZ algebraic notation.
% Features include spaces, rotated, blank, and concealed tiles, as well as red fives.
% The size of the mahjong tiles can be controlled using a package option and an optional argument of |\mahjong|.
% It is primarily aimed at Riichi (aka. Japanese) Mahjong but can be used to typeset any style of mahjong.
% However, flower tiles and jokers are currently missing.
% \end{abstract}
%
% \begin{documentation}
% \section{Introduction}
% Mahjong is a tile-based game originating from China which is popular in East and South-East Asia and has since spread throughout the world.
% The \textsf{mahjong} package provides an interface for typesetting mahjong tiles and hands using MPSZ algebraic notation.
% This documentation assumes familiarity with the game in general but none of its many styles.
% Nonetheless, some basic terms will be defined because of differing vocabulary among players.
% 
% \newcommand{\rmahjong}[1]{\raisebox{-.4\height}{\mahjong{#1}}}
% \section{Mahjong Tiles}
% \subsection{Suited Tiles}
% The suited tiles are referred to as follows:
% 
% \begin{tabular}{@{} l l @{}}
% \toprule
% \textbf{Suit} & \textbf{Tiles} \\
% \midrule
% Bamboo & \rmahjong{1234506789s} \\
% Dots & \rmahjong{1234506789p} \\
% Character & \rmahjong{1234506789m} \\
% \bottomrule
% \end{tabular}
% 
% Suited tiles are referred to using the pattern \meta{value} \meta{suit}.
% For instance, \mahjong{4s} is called \textit{4~Bamboo}.
% 
% \subsection{Honor Tiles}
% This documentation refers to the seven honor tiles as follows:
%
% \begin{tabular}{@{}c c c c@{}}
% \toprule
% \multicolumn{4}{c}{\bfseries Winds} \\
% \mahjong{1z} & \mahjong{2z} & \mahjong{3z} & \mahjong{4z} \\
% East Wind (E) & South Wind (S) & West Wind (W) & North Wind (N) \\
% \midrule
% \multicolumn{4}{c}{\bfseries Dragons} \\
% \mahjong{5z} & \mahjong{6z} & \mahjong{7z} & \\
% White Dragon & Green Dragon & Red Dragon & \\

% \caption[MPSZ reference]{MPSZ notation reference. Each tile is identified by its column's number and its row's letter.}

% MPSZ notation assigns each tile an identifier consisting of a digit and a letter (\cref{tab:mpszref}).
% For suited tiles, the digit corresponds to the tile's value and the letter to its suit, Bamboo (|s|), Dots (|p|) or Character (|m|).
% For instance, |2m| identifies \mahjong{2m} (2~Character).
% The only exception ot this rule are red fives, whose numeric value is 0.
% Red 5 Bamboo, for example, has identifier |0s|.
% Honor tiles are assigned the "suit" |z|, with |1z| -- |4z| corresponding to E, S, W and N, and |5z| -- |7z| to the white, green and red dragon, respectively.
% 
% Collections of tiles, such as melds or hands, are represented by concatenating the identifiers of the tiles they comprise.
% For instance, |3s4s5s| corresponds to \mahjong{3s4s5s}.
% Groups of tiles sharing the same suit can be abbreviated by omitting all but the last suit identifier.
% The above example can also be expressed as |345s|.
% Spaces are ignored and the notation is case-insensitive.
%
% \subsection{Extensions}
% \paragraph{Spaces.} Spaces can be inserted using |-|:
% |444s-567s| produces \mahjong{444s-567s}.
%
% \paragraph{Concealed Tiles.} \mahjong{X} Concealed (or face-down) tiles are represented by |X|.
% They don't need a suit identifier and don't act as one.
% |123s X 456s| and |123 X 456s| are therefore equivalent.
%
% \paragraph{Blank Tiles.} \mahjong{?} Blank or unknown tiles are represented by |?|.
% Just like concealed tiles, they don't change the current suit.
% |123s ? 456s| and |123 ? 456s| are equivalent, for instance.
%
% \paragraph{Rotation.} Inserting an apostrophe (|'|) rotates the \textit{preceeding} tile counter-clockwise.
% For instance, |6'66m| is rendered as \mahjong{6'66m}. 
% This can only be done once per tile, i.e. it is not possible to rotate them 180\degree{} or 270\degree{}.
% When you want to rotate the last tile of a group, it doesn't matter whether the apostrophe appears before or after the suit, so |77'm| and |77m'| are equivalent.
%
%
% \paragraph{Rotation and Stacking.} Quotes (|"|) cause the \textit{preceeding} tile to be rendered as two rotated and stacked tiles.
% For instance, |77"7z| produces \mahjong{77"7z}.
%
% \section{Typesetting Mahjong Tiles in Your Document}
% \DescribeMacro{\mahjong}
% The main interface is |\mahjong| \oarg{height} \marg{hand}.
% \meta{hand} refers to a tile sequence in MPSZ notation as discussed above and \meta{height} specifies the height of the rendered mahjong tiles.
% If \meta{height} is not specified, the default height is used.
%
% \DescribeMacro{\mahjong_typeset_hand:n} \DescribeMacro{\mahjong_typeset_hand:x}
% The \LaTeX~3 interface for rendering mahjong tiles are |\mahjong_typeset_hand:n| and its variants.
% This macro accepts the hand to be rendered in MPSZ notation.
% The height can be specified by setting |\l_mahjong_tile_height| \DescribeMacro{\l_mahjong_tile_height} and the default height is saved in |\g_mahjong_default_height|. \DescribeMacro{\g_mahjong_default_height}
% 
% The default height can be set using the package's |height| parameter.
% For instance, |\usepackage[height=2\baselineskip]{mahjong}| sets the default size of mahjong tiles to double the value of |\baselineskip| in the context they are rendered in.
% The parameter defaults to |\baselineskip|.
