\subsection{Backgrounds}
+%<*en>
Traditionally, ASCII \pTeX, an extension of \TeX, and its derivatives
are used to typeset Japanese documents in \TeX. \pTeX\ is an engine
extension of \TeX: so it can produce high-quality Japanese documents
\LuaTeX. So there is no need to modify sources of engines to
support Japanese typesetting: to do this, we only have to write Lua
scripts for appropriate callbacks.

+%</en>
+%<*ja>
+従来，「\TeX を用いて日本語組版を行う」といったとき，エンジンとしては
+ASCII \pTeX やそれの拡張物が用いられることが一般的であった．\pTeX は\TeX
+のエンジン拡張であり，（少々仕様上不便な点はあるものの）商業印刷の分野に
+も用いられるほどの高品質な日本語組版を可能としている．だが，それは弱点に
+もなってしまった：\pTeX という（組版的に）満足なものがあったため，海外で
+行われている数々の\TeX の拡張──例えば\eTeX や\pdfTeX ──や，TrueType,
+OpenType, Unicodeといった計算機で日本語を扱う際の状況の変化に追従すること
+を怠ってしまったのだ．
+
+ここ数年，若干状況は改善されてきた．現在手に入る大半の\pTeX バイナリでは
+外部UTF-8入力が利用可能となり，さらにUnicode化を推進し，\pTeX の内部処理
+までUnicode化した\upTeX も開発されている．また，\pTeX に\eTeX 拡張をマー
+ジした\epTeX も登場し，\TeX\ Live\ 2011では\pLaTeX が\epTeX の上で動作す
+るようになった．だが，\pdfTeX 拡張（pdf直接出力やmicro-typesetting）を
+\pTeX に対応させようという動きはなく，海外とのgapは未だにあるのが現状であ
+る．
+
+しかし，\LuaTeX の登場で，状況は大きく変わることになった．Luaコードで
+`callback'を書くことにより，\LuaTeX の内部処理に割り込みをかけることが可
+能となった．これは，エンジン拡張という真似をしなくても，Luaコードとそれに
+関する\TeX マクロを書けば，エンジン拡張とほぼ同程度のことができるようになっ
+たということを意味する．\LuaTeX-jaは，このアプローチによってLuaコード・
+\TeX マクロによって日本語組版を\LuaTeX の上で実現させようという目的で開発
+が始まったパッケージである．

\subsection{Major Changes from \pTeX}
+%<*en>
The \LuaTeX-ja package is under much influence of \pTeX\ engine. The initial
target of development was to implement features of \pTeX. However,
\emph{\LuaTeX-ja is not a just porting of \pTeX; unnatural
specifications/behaviors of \pTeX\ were not adopted}.
+%</en>
+
+%<*ja>
+\LuaTeX-jaは，\pTeX に多大な影響を受けている．初期の開発目標は，\pTeX の機
+能をLuaコードにより実装することであった．しかし，開発が進むにつれ，\pTeX
+の完全な移植は不可能であり，また\pTeX における実装がいささか不可解になっ
+ているような状況も発見された．そのため，\textbf{\LuaTeX-ja は，もはや
+\pTeX の完全な移植は目標とはしない．\pTeX における不自然な仕様・挙動があ
+れば，そこは積極的に改める．}

attributes of Japanese fonts.

As described in Subsection~\ref{ssec-ltx}, \LuaTeX-ja simply adopted
\texttt{plfonts.dtx} in \pLaTeXe\ for the Japanese patch for NFSS2.
+For an convinience, we will describe
+commands which are not described in Subsection~\ref{ssub-chgfnt}.
+
+\begin{cslist}%
+\item[DeclareYokoKanjiEncoding\{<encoding>\}\{<text-settings>\}\{<math-settings>\}]
+In NFSS2 under \LuaTeX-ja, distinction between alphabetic font families
+ and Japanese font families is only made by its
+ encoding. For example, encodings OT1 and T1 are for
+ alphabetic font families, and a Japanese font family cannot
+ have these encodings. This command defines a new encoding
+ scheme for Japanese font family (in horizontal direction).
+

+\item[DeclareKanjiSubstitution\{<encoding>\}\{<family>\}\{<series>\}\{<shape>\}]
+\item[DeclareErrorKanjiFont\{<encoding>\}\{<family>\}\{<series>\}\{<shape>\}\{<size>\}]
+
+The above 3~commands are just the counterparts for \verb+DeclareFontEncodingDefaults+ and~others.
+
+\item[reDeclareMathAlphabet\{<unified-cmd>\}\{<al-cmd>\}\{<ja-cmd>\}]
+和文・欧文の数式用フォントファミリを一度に変更する命令を作成する．

+ <unified-cmd>を（再）定義する．実際の使用では<unified-cmd>と
+ <al-cmd>に同じものを指定する，すなわち，<al-cmd>に和文側も変
+ 更させるようにするのが一般的と思われる．
+
+本コマンドの使用については，\pLaTeX 配布中の\texttt{plfonts.dtx}に詳しく
+ 注意点が述べられているので，そちらを参照されたい．
+
+\item[DeclareRelationFont\{<ja-encoding>\}\{<ja-family>\}\{<ja-series>\}\{<ja-shape>\}\\
+ \hfill\{<al-encoding>\}\{<al-family>\}\{<al-series>\}\{<al-shape>\}]
