+\section{The History of Snowman in Unicode}
+
+In October 1991, the first volume of the Unicode standard was published. Since then,
+there was a code point assigned to a character ``snowman''; \verb:U+2603:.
+\begin{quote}
+ \verb:U+2603 SNOWMAN:\\
+ = snowy weather
+\end{quote}
+It seems that the shape of its reference glyph in Unicode 1.0.0 was taken from ``Ryumin'',
+which was developed by Morisawa (a famous font vendor in Japan).
+\begin{figure}
+%\includegraphics[width=0.3\textwidth]{}
+\end{figure}
+A few years later, the reference glyph has sometimes been changed to another; however,
+there had been only one ``snowman'' in Unicode until 2009.
+\begin{figure}
+%\includegraphics[width=0.3\textwidth]{}
+\end{figure}
+
+In October 2009, Unicode 5.2 was published. In this volume, two ``snowman'' code points
+were added; \verb:U+26C4: and \verb:U+26C7:.
+\begin{quote}
+ \verb:U+26C4 SNOWMAN WITHOUT SNOW:\\
+ = light snow\\
+ \verb:U+26C7 BLACK SNOWMAN:\\
+ = heavy snow
+\end{quote}
+According to the code chart, the origin of these two characters is ARIB STD-B24
+(Data Coding and Transmission Specification for Digital Broadcasting;\footnote{%
+\url{http://www.arib.or.jp/tyosakenkyu/kikaku_hoso/hoso_std-b024.html}; Abstract in PDF format
+(both \href{http://www.arib.or.jp/tyosakenkyu/kikaku_sample/sample-std-b24-1-6.3.pdf}{Japanese}
+and \href{http://www.arib.or.jp/english/html/overview/doc/6-STD-B24v5_2-1p3-E1.pdf}{English}) are
+available.}), which was established by Association of Radio Industries and Business in
+Japan. Since then, it can be said that the old code point \verb:U+2603: has been given
+an implicit meaning of ``\verb:SNOWMAN WITH SNOW:''. The reference glyphs were also changed
+at that time.
+\begin{figure}
+%\includegraphics[width=0.3\textwidth]{}
+\end{figure}
+
+\section{Variation of Snowman among Actual Fonts}
+
+Since the shapes of the reference glyphs used in the Unicode code charts are not
+prescriptive, the actual fonts have a wide variety of glyph designs. However, when it
+comes to snowmen, the variation between fonts is enormous. This variation is very
+interesting, however, on the other hand, problematic.
+
+Table \ref{table:actualfonts} shows the variety of ``snowman'' in actual fonts.
+\begin{table}[tbp]

+\end{table}
+The snowman in ``IPA Mincho (IPA明朝)'' from Information-technology Promotion Agency is very similar
+to the one in ``Ryumin (リュウミン)'' from Morisawa. However, in ``MS Mincho (MS 明朝)'' from Microsoft,
+the snowman wears a black hat instead of white one. In ``Kozuka Mincho (小塚明朝)'' from Adobe Systems Inc.,
+he/she wears a muffler instead of a hat. Moreover, it doesn't snow in ``Hiragino Mincho (ヒラギノ明朝)'' from
+SCREEN Graphic and Precision Solutions Co., Ltd. It is natural that some fonts developed before 2009 have
+a ``snowman without snow'' glyph in the code point \verb:U+2603:, however, it can be a problem when we
+have to transfer the exact information to others.
+
+\section{Introduction to \Lpack{scsnowman} Package}
+
+The \LaTeX\ package \Lpack{scsnowman} provides a command \verb+\scsnowman+, which can
+display many variants of snowmen. This package depends on Ti\emph{k}Z package for drawing
+snowman images.
+
+To use this package, load it in preamble:
+\begin{quote}\begin{verbatim}
+\usepackage{scsnowman}
+\end{verbatim}\end{quote}
+In the main document, use \verb+\scsnowman+ command to print a snowman: \scsnowman.
+By default, the snowman is ``plain'' style, without any decoration such as snow, a hat or
+a muffler.
+
+\section{Command Options}
+
+You can customize the style of a snowman using the optional argument. The syntax is
+\begin{quote}
+\verb+\scsnowman[+\emph{$\langle$key-value list$\rangle$}\verb+]+
+\end{quote}
+
+\subsection{Scaling and Adjustment Options}
+
+The following \emph{key}s are available:
+\begin{quote}
+ \Lopt{scale}, \Lopt{adjustbaseline}
+\end{quote}
+The key \Lopt{scale} takes a scale factor. The origin of scaling is set at the lower
+left corner of the bounding box. For example, \verb+\scsnowman+,
+\verb+\scsnowman[scale=3]+ and \verb+\scsnowman[scale=5]+ give:
+\begin{quote}\begin{minipage}{.9\textwidth}
+\scsnowman\scsnowman[scale=3]\scsnowman[scale=5]\quad
+with visualized bounding boxes:
+\fboxsep0pt\fbox{\scsnowman}\fbox{\scsnowman[scale=3]}\fbox{\scsnowman[scale=5]}
+\end{minipage}\end{quote}
+When the key \Lopt{adjustbaseline} is specified (or, \Lopt{adjustbaseline=true}),
+the base line of the in-line snowman will be adjusted to that of the surrounding texts.
+This will be helpful when a snowman appears to be ``floating in the air.''\\[1ex]
+\begin{minipage}{.55\textwidth}\begin{verbatim}
+ Text,
+ \scsnowman[scale=1]%
+ \scsnowman[scale=4]%
+ \scsnowman[scale=7],
+ T.\par
+ Text,
+ \scsnowman[adjustbaseline,scale=1]%
+ \scsnowman[adjustbaseline,scale=4]%
+ \scsnowman[adjustbaseline,scale=7],
+ T.
+\end{verbatim}\end{minipage}
+\begin{minipage}{.4\textwidth}
+ Text,
+ \scsnowman[scale=1]%
+ \scsnowman[scale=4]%
+ \scsnowman[scale=7],
+ T.\par
+ Text,
+ \scsnowman[adjustbaseline,scale=1]%
+ \scsnowman[adjustbaseline,scale=4]%
+ \scsnowman[adjustbaseline,scale=7],
+ T.
+\end{minipage}
+
+\subsection{Design Options}
+
+Following \emph{key}s take a \emph{value} which specifies color. When the \emph{value} is omitted,
+it reacts to the surrounding text color:
+\begin{quote}
+ \Lopt{body}, \Lopt{eyes}, \Lopt{mouth}, \Lopt{nose}, \Lopt{sweat}, \Lopt{arms},
+ \Lopt{hat}, \Lopt{muffler}, \Lopt{buttons}, \Lopt{snow}, \Lopt{note}, \Lopt{broom}
+\end{quote}
+The following \emph{key}s require one specific \emph{value}:
+\begin{quote}
+ \Lopt{shape}, \Lopt{mouthshape}
+\end{quote}
+
+The key \Lopt{shape} specifies the outline shape of the snowman body.
+Currently, only \Lopt{shape=normal} is officially available, but you can define and use other shapes
+using \verb+\usescsnowmanlibrary+ command (described later, section \ref{usescsnowmanlibrary}).
+
+The key \Lopt{mouthshape} takes one of the followings: \Lopt{smile}, \Lopt{tight} or \Lopt{frown}.
+
+Here are some examples:\\[1ex]
+\begin{minipage}{.7\textwidth}\begin{verbatim}
+ \scsnowman[scale=2,body,hat=red,muffler=blue]
+ \scsnowman[scale=3,hat,snow,arms,buttons,note]
+ \scsnowman[scale=2,muffler=red,arms,broom=brown]
+ \scsnowman[scale=2,mouthshape=frown,hat=green]
+\end{verbatim}\end{minipage}
+\begin{minipage}{.25\textwidth}
+ \scsnowman[scale=2,body,hat=red,muffler=blue]
+ \scsnowman[scale=3,hat,snow,arms,buttons,note]
+ \scsnowman[scale=2,muffler=red,arms,broom=brown]
+ \scsnowman[scale=2,mouthshape=frown,hat=green]
+\end{minipage}\\[1ex]
+\begin{minipage}{.7\textwidth}\begin{verbatim}
+ {\color{blue}
+ \scsnowman[scale=2,body,hat=red,muffler=blue]
+ \scsnowman[scale=2,hat,snow,arms,buttons,note]
+ \scsnowman[scale=3,muffler=red,arms,broom=brown]
+ \scsnowman[scale=2,mouthshape=frown,hat=green]}
+\end{verbatim}\end{minipage}
+\begin{minipage}{.25\textwidth}
+ {\color{blue}
+ \scsnowman[scale=2,body,hat=red,muffler=blue]
+ \scsnowman[scale=2,hat,snow,arms,buttons,note]
+ \scsnowman[scale=3,muffler=red,arms,broom=brown]
+ \scsnowman[scale=2,mouthshape=frown,hat=green]}
+\end{minipage}
+
+\section{Changing the Default}
+
+The package default is the ``plain'' style snowman. This default can be changed by using
+\verb+\scsnowmandefault+ command. The syntax is
+\begin{quote}
+\verb+\scsnowmandefault{+\emph{$\langle$key-value list$\rangle$}\verb+}+
+\end{quote}
+The available \emph{key}s are the same as those in \verb+\scsnowman+.
+
+Here are some examples:\\[1ex]
+\begin{minipage}{.6\textwidth}\begin{verbatim}
+ \scsnowmandefault{scale=5,hat=red}
+ \scsnowman
+ \scsnowman[body,muffler=blue,arms]
+ \scsnowman[hat=green,snow,nose=orange]
+\end{verbatim}\end{minipage}
+\begin{minipage}{.35\textwidth}
+ \scsnowmandefault{scale=5,hat=red}
+ \scsnowman
+ \scsnowman[body,muffler=blue,arms]
+ \scsnowman[hat=green,snow,nose=orange]
+\end{minipage}
+
+\section{Adding User-defined Snowman Shapes}\label{usescsnowmanlibrary}
+
+Any users can define and use custom snowman shape definitions.
+Here is a description of adding a shape named \Lopt{myfavorite}.
+\begin{enumerate}
+ \item Prepare a snowman definition file \texttt{scsnowman-myfavorite.def}
+ and put it into \verb+$TEXMF+ tree (e.g. \verb+texmf-local/tex/latex/scsnowman/+).
+ For the format of snowman definition files, please refer to \texttt{scsnowman-normal.def}.
+ \item Use \verb+\usescsnowmanlibrary+ command (don't forget \emph{sc}!) to load it.
+\begin{verbatim}
+ \usepackage{scsnowman}
+ \usescsnowmanlibrary{myfavorite}
+\end{verbatim}
+ \item You can use the shape by \verb+\scsnowman[shape=myfavorite]+ command.
+\end{enumerate}
+If you have created a fancy snowman, please contact me, so that I can incorporate it
+into the official release!
+
+\section{Funny Usages}
+
+\subsection{Changing Item Labels and QED Symbols}
+
+For those who want more snowmen in the documents, currently \Lpack{scsnowman} provides
+the following additional commands:
+\begin{quote}
+\verb+\makeitemsnowman+:\\
+ \makeitemsnowman
+ Change item labels in \Lopt{itemize} environment to snowmen
+ {\labelitemi\labelitemii\labelitemiii\labelitemiv}.
+ \makeitemother
+ The command \verb+\makeitemother+ restores the default,
+ usually {\labelitemi\labelitemii\labelitemiii\labelitemiv}.\par
+\verb+\makeqedsnowman+:\\
+ \makeqedsnowman
+ Change the QED symbol in \Lopt{proof} environment to a snowman {\qedsymbol}.
+ The package \Lpack{amsthm} is required.
+ \makeqedother
+ The command \verb+\makeqedother+ restores the default, usually {\qedsymbol}.
+\end{quote}
+These commands can be used wherever you want, and are effective within the current group.
+
+Here are some examples:\\[1ex]
+\begin{minipage}{.5\textwidth}\begin{verbatim}
+ \begin{itemize}
+ \makeitemsnowman
+ \item Foo X.
+ \begin{itemize}
+ \item Bar A.
+ \begin{itemize}
+ \item Baz P. \item Baz Q.
+ \end{itemize}
+ \item Bar B. \item Bar C.
+ \end{itemize}
+ \end{itemize}
+\end{verbatim}\end{minipage}
+\begin{minipage}{.45\textwidth}
+ \begin{itemize}
+ \makeitemsnowman
+ \item Foo X.
+ \begin{itemize}
+ \item Bar A.
+ \begin{itemize}
+ \item Baz P. \item Baz Q.
+ \end{itemize}
+ \item Bar B. \item Bar C.
+ \end{itemize}
+ \end{itemize}
+\end{minipage}\\[1ex]
+\begin{minipage}{.55\textwidth}\begin{verbatim}
+ \makeqedsnowman
+ \begin{theorem}
+ Given two line segments whose
+ lengths are $a$ and $b$ respectively,
+ there is a real number $r$ such that
+ $b=ra$.
+ \end{theorem}
+ \begin{proof}
+ To prove it by contradiction try and
+ asuume that the statement is false,
+ proceed from there and at some point
+ you will arrive to a contradiction.
+ \end{proof}
+\end{verbatim}\end{minipage}
+\begin{minipage}{.45\textwidth}
+ \makeqedsnowman
+ \begin{theorem}
+ Given two line segments whose
+ lengths are $a$ and $b$ respectively,
+ there is a real number $r$ such that
+ $b=ra$.
+ \end{theorem}
+ \begin{proof}
+ To prove it by contradiction try and
+ asuume that the statement is false,
+ proceed from there and at some point
+ you will arrive to a contradiction.
+ \end{proof}
+\end{minipage}\medskip
+
+The names of these commands are, of course, named after the \LaTeX\ \verb+\makeatletter+
+and \verb+\makeatother+;-)
+
+\subsection{Drawing ``\emph{Kagami-mochi}''}
+
+Using \Lpack{scsnowman} package, you can also draw ``\emph{kagami-mochi}''
+(mirror rice cake). It is a traditional Japanese New Year decoration,
+which usually consists of two round ``\emph{mochi}'' (rice cakes), the smaller
+placed atop the larger, and a ``\emph{daidai}'' (a Japanese bitter orange)
+with an attached leaf on top.
+
+Following \emph{key}s are implemented for this usage:\footnote{Strictly speaking,
+the orange on top of rice cakes should be ``\emph{daidai}''; however,
+a ``\emph{mikan}'' is often substituted for the original ``\emph{daidai}''.}
+\begin{quote}
+ \Lopt{mikan}, \Lopt{leaf}
+\end{quote}
+The \emph{key} \Lopt{leaf} is effective only when \Lopt{mikan} is specified.
+Here is an example:\\[1ex]
+\begin{minipage}{.85\textwidth}\begin{verbatim}
+ \scsnowmandefault{scale=5.5}
+ \scsnowman[eyes=false,mouth=false,mikan=orange,leaf=green]
+\end{verbatim}\end{minipage}
+\begin{minipage}{.1\textwidth}
+ \scsnowmandefault{scale=5.5}
+ \scsnowman[eyes=false,mouth=false,mikan=orange,leaf=green]
+\end{minipage}
+
+\subsection{Replacing All ``8'' with Snowmen}
+
+You can replace all ``8'' inside an arabic number expression with snowmen
+\scsnowman\ by using \verb+\scsnowmannumeral+.
+Here is an example:\\[1ex]
+\begin{minipage}{.85\textwidth}\begin{verbatim}
+ \scsnowmandefault{adjustbaseline}\scsnowmannumeral{18882}
+ \scsnowmannumeral[muffler=blue,scale=1.5]{4283859}
+\end{verbatim}\end{minipage}
+\begin{minipage}{.1\textwidth}
+ \scsnowmandefault{adjustbaseline}\scsnowmannumeral{18882}
+ \scsnowmannumeral[muffler=blue,scale=1.5]{4283859}
+\end{minipage}\medskip
+
+You can also replace all ``8'' inside the page numbering with snowmen
+\scsnowman\ by adding \verb+\pagenumbering{enumsnowman}+.
+This documentation itself is an example!
