+# ascmac
+
+The bundle provides boxes and picture macros, derived from
+Japanese pLaTeX distribution. These macros and fonts were
+originally developed by ASCII MEDIA WORKS, and now
+maintained by Japanese TeX Development Community.
+
+## Changes from the original ASCII edition
+
+See the documents (ascmac.pdf) for more information.
+
+- Support pdfLaTeX, XeLaTeX and LuaLaTeX.
+- Fix several bugs in `\oval` drawings, which are used in
+  `screen` environment and `\keytop`.
+- Made compatible with the package "pict2e".
+
+## Repository
+
+The bundle is maintained on GitHub:
+https://github.com/texjporg/ascmac

+% \section{はじめに}
+%
+% \textsf{ascmac}パッケージは、\LaTeXe{}の標準機能の範囲で、図や罫線で
+% 囲んだボックスを出力する命令などを提供します。\textsf{ascmac}パッケージ
+% の実体は\textsf{tascmac}パッケージですが、これはもともと古いp\LaTeX{}で
+% 配布されていた横組専用\textsf{ascmac}パッケージと、それを縦組に対応させ
+% た\textsf{tascmac}パッケージを統合した名残です。
+%
+% このドキュメントは、アスキーによって配布されている 2006/07/14 バージョン
+% から派生して、日本語\TeX{}開発コミュニティによって開発されているバージョン
+% のために新たに書かれました。コミュニティ版では、オリジナルのアスキー版の
+% コードを元に、いくつかのバグ修正と他のパッケージとの互換性を改善しました。
+% また、v2.0c以降ではpdf\LaTeX{}などのエンジンもサポートしました。
+%
+%\iffalse
+% The package \textsf{ascmac} provides fancy boxes etc., within the scope
+% of native \LaTeXe\ picture commands (thus driver-independent).
+% This package was originally part of Japanese \pLaTeX, but now it
+% supports pdf\LaTeX, Xe\LaTeX\ and Lua\LaTeX.
+%\fi
+%
+% \section{使いかた}
+%
+% \subsection{環境型の命令}
+%
+% \textsf{ascmac}パッケージが提供する環境型の命令は4種類あります。それぞれ
+% テキストなどを罫線枠で囲んで出力します。
+%
+% これらの環境は、すべて横幅がその時点での |\linewidth| の値になりますの
+% で、ボックスの幅を変更したい場合は |minipage| 環境などで囲んでください。
+% 縦の長さは、自動的に内容に合わせて調整されます。 \medskip
+%
+% \DescribeEnv{boxnote}
+% |boxnote| 環境は、破ったメモ用紙のような雰囲気のボックスを作ります。
+% 破ったような形の罫線は、ascgrpフォントを使って実現されています。
+%
+% \begin{boxnote}
+% ボックスノート環境です。
+% \end{boxnote}
+% は、以下の入力から得られます。
+%\begin{verbatim}
+% \begin{boxnote}
+% ボックスノート環境です。
+% \end{boxnote}
+%\end{verbatim}
+%
+% \DescribeEnv{screen}
+% |screen| 環境は、四隅が丸い囲み枠の中にテキストを入れます。
+% オプション引数として |0| から |8| の整数値を指定すれば、四隅の丸みの
+% 具合を変更することができます。整数値を大きくするにつれて丸みは小さく
+% なっていきます。省略した場合は |0| とみなされます。
+%
+% \begin{screen}
+% 四隅が丸い囲み枠です。
+% \end{screen}
+% \begin{screen}[4]
+% 四隅が丸い囲み枠です。
+% \end{screen}
+% は、以下の入力から得られます。
+%\begin{verbatim}
+% \begin{screen}
+% 四隅が丸い囲み枠です。
+% \end{screen}
+% \begin{screen}[4]
+% 四隅が丸い囲み枠です。
+% \end{screen}
+%\end{verbatim}
+%
+% \DescribeEnv{itembox}
+% |itembox| 環境は |screen| 環境に似ていますが、上端の罫線のところにタイトル
+% を出力することができます。また、オプション引数 |l|, |c|, |r| でタイトル
+% の出力位置を左、中央、右と指定できます。省略した場合は中央になります。
+%
+% \begin{itembox}[l]{タイトル}
+% 項目ボックスです。
+% \end{itembox}
+% は、以下の入力から得られます。
+%\begin{verbatim}
+% \begin{itembox}[l]{タイトル}
+% 項目ボックスです。
+% \end{itembox}
+%\end{verbatim}
+%
+% \DescribeEnv{shadebox}
+% |shadebox| 環境は、影付きボックスの中にテキストを入れます。
+% 影の幅は |\shaderule| パラメータで規定され、デフォルトは5ptです。
+%
+% \begin{shadebox}
+% 影付きのボックスです。
+% \end{shadebox}
+% は、以下の入力から得られます。
+%\begin{verbatim}
+% \begin{shadebox}
+% 影付きのボックスです。
+% \end{shadebox}
+%\end{verbatim}
+%
+% \subsection{網掛け命令}
+%
+% 網掛けをする命令が3種類用意されています。|\mask| 命令は、引数の内容の部分
+% に網を掛けます。|\maskbox| 命令と |\Maskbox| 命令は、幅と高さを指定して
+% 網掛けすることができます。そして、|\maskbox| 命令と |\Maskbox| 命令の違い
+% は、後者のみボックスの周りに罫線を引くという点です。
+%
+% これらの命令は、いずれもascgrpフォントに収録されている網掛けパターンの
+% 文字を並べることで網掛けを実現しています。

+% \DescribeMacro{\mask}
+% |\mask| 命令は、第1引数が網掛けをする内容で、第2引数が網掛けパターンを
+% 示す記号（AからK）です。
+%
+% \begin{center}
+% \mask{網掛け例1}{A} \hfil \mask{網掛け例2}{C}
+% \end{center}
+% は、以下の入力から得られます。
+%\begin{verbatim}
+% \mask{網掛け例1}{A} \hfil \mask{網掛け例2}{C}
+%\end{verbatim}
+%
+% \DescribeMacro{\maskbox}
+% |\maskbox| 命令は5つの引数を持ち、それぞれボックスの幅、高さ、
+% 網掛けパターン、出力位置、網掛けをする内容です。出力位置は |l|, |c|, |r| の
+% いずれかで、それぞれ左、中央、右に出力します。
+%
+% \begin{center}
+% \maskbox{25em}{4em}{E}{c}{幅を指定した網掛けボックス}
+% \end{center}
+% は、以下の入力から得られます。
+%\begin{verbatim}
+% \maskbox{25em}{4em}{E}{c}{幅を指定した網掛けボックス}
+%\end{verbatim}
+%
+% \DescribeMacro{\Maskbox}
+% |\Maskbox| 命令は |\maskbox| 命令と同様の引数を持ちますが、網掛けをする内容の
+% 指定の前、すなわち5番目の引数として、ボックスを囲む罫線の太さも指定します。
+% したがって、全部で6つの引数を持ちます。
+%
+% \begin{center}
+% \Maskbox{30em}{4em}{A}{c}{1pt}{幅を指定した罫線付き網掛けボックス}
+% \end{center}
+% は、以下の入力から得られます。
