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
without using very complicated macros. But this point is a mixed
blessing: \pTeX\ is left behind from other extensions of \TeX,
-especially \eTeX\ and pdf\TeX, and from changes about
+especially \eTeX\ and \pdfTeX, and from changes about
Japanese processing in computers (\textit{e.g.}, the UTF-8 encoding).
-
-Recently extensions of \pTeX, namely \upTeX\ (Unicode-implementation
-of \pTeX) and \epTeX\ (merging of \pTeX\ and
-\eTeX\ extension), have developed to fill those gaps to some
-extent, but gaps still exist.
-
-However, the appearance of \LuaTeX\ changed the whole situation. With
-using Lua `callbacks', users can customize the internal processing of
-\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.

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>
The followings are major changes from \pTeX:
+%</en>
+%<*ja>
+以下は \pTeX からの主な変更点である．
+%</ja>
+
\begin{itemize}
+%<*en>
\item A Japanese font is a tuple of a `real' font, a Japanese font
metric (\textbf{JFM}, for short), and an optional string called
`variation'.
+%</en>
+%<*ja>
+\item 和文フォントは「実際の」フォント，和文フォントメトリック（JFM と呼ぶ），そ
+ して `variation' と呼ばれる文字列の組である．
+%</ja>
-\item In \pTeX, a linebreak after Japanese character is ignored (and
- doesn't yield a space), since linebreaks (in source files) are
+%<*en>
+\item In \pTeX, a line break after Japanese character is ignored (and
+ doesn't yield a space), since line breaks (in source files) are
permitted almost everywhere in Japanese texts. However, \LuaTeX-ja
doesn't have this function completely, because of a specification
of \LuaTeX.
+%</en>
+%<*ja>
+\item 日本語の文書中では改行はほとんどどこでも許されるので，\pTeX では和文文字
+ 直後の改行は無視される（スペースが入らない）ようになっていた．しかし，
+ \LuaTeX-ja では \LuaTeX の仕様のためにこの機能は完全には実装されていない．
+%</ja>
+
+%<*en>
\item The insertion process of glues/kerns between two Japanese
characters and between a Japanese character and other characters
(we refer these glues/kerns as \textbf{JAglue}) is rewritten from
scratch.
+%</en>
+%<*ja>
+\item 2つの和文文字の間，和文文字と欧文文字の間に入るグルー／カーン
+ （\textbf{JAglue} と呼ぶ）の挿入処理が0から書き直されている．
+%</ja>
\begin{itemize}
+%<*en>
\item As \LuaTeX's internal character handling is `node-based'
(\textit{e.g.}, \verb+of{}fice+ doesn't prevent ligatures), the
insertion process of \textbf{JAglue} is now `node-based'.
+%</en>
+%<*ja>
+\item \LuaTeX の内部での文字の扱いが「ノードベース」になっているように（例えば，
+ \verb+of{}fice+ で合字は抑制されない），\textbf{JAglue} の挿入処理も
+ 「ノードベース」である．
+%</ja>
+
+%<*en>
\item Furthermore, nodes between two characters which have no effects in
- linebreak (\textit{e.g.}, \verb+\special+ node) are ignored in the
- insertion process.
-\item In the process, two Japanese fonts which differ in their `real'
- fonts only are identified.
+ line break (\textit{e.g.}, \verb+\special+ node) and kerns from
+ italic correction are ignored in the insertion process.
+%</en>
+%<*ja>
+\item さらに，2つの文字の間にある行末では効果を持たないノード（例えば
+ \verb+\special+ ノード）や，イタリック補正に伴い挿入されるカーンは

+\item \emph{Caution: due to above two points, many methods which did the

+ effective anymore.} In concrete terms, the following two methods are not effective anymore:
