\maketitle

\begin{abstract}
\noindent
The \pkg{arabdoc} collection provides a one-line setup for Arabic right-to-left typesetting in XeLaTeX. It replaces 15--25 lines of fragile preamble (package loading order, font configuration, caption overrides, section formatting) with a single \cmd{usepackage} call. The suite includes document classes, glossary support, and bibliography styles.
\end{abstract}

\tableofcontents

\section{Overview}

The suite consists of four packages:

\begin{longtable}{lll}
\toprule
\textbf{Package} & \textbf{Type} & \textbf{Purpose} \\
\midrule
\pkg{arabdoc-setup} & \texttt{.sty} & Core RTL stack: bidi + polyglossia + fonts + captions \\
\pkg{arabdoc} & \texttt{.cls} & Document classes: article, book, thesis, report \\
\pkg{arabdoc-glossary} & \texttt{.sty} & Arabic glossary and acronym styles \\
\pkg{arabdoc-bib} & \texttt{.sty} & Arabic bibliography support (biblatex) \\
\bottomrule
\end{longtable}

\section{The Problem}

Typesetting Arabic in LaTeX requires a specific package loading order. Getting it wrong causes compilation errors:

\begin{quote}
\texttt{! Package bidi Error: Oops! you have loaded package hyperref after bidi}
\end{quote}

A correct Arabic preamble requires 15--25 lines with exact ordering:

\begin{english}\begin{verbatim}
\usepackage{bidi}                              % must be before polyglossia
\usepackage[no-math]{fontspec}                 % must be after bidi
\usepackage[quiet]{polyglossia}                % must be after fontspec
\setmainfont[Scale=1]{Amiri-Regular.ttf}
\newfontfamily\arabicfont[Script=Arabic]{...}
\newfontfamily\englishfont[Scale=0.95]{...}
\setdefaultlanguage[calendar=gregorian]{arabic}
\setotherlanguage{english}
\usepackage[breaklinks,hidelinks]{hyperref}    % must be last
\addto\captionsarabic{...}                     % 10+ caption overrides
\titleformat{\section}{...}                    % section formatting
\newcolumntype{L}[1]{...}                      % table column types
\setstretch{1.5}                               % line spacing
\end{verbatim}\end{english}

One mistake in this order breaks the entire document. \pkg{arabdoc-setup} encapsulates all of this.

\end{quote}

Legal document with colored links:
\begin{quote}
\texttt{\char`\\usepackage[amiri,captions,legal-sections,colorlinks]\{arabdoc-setup\}}
\end{quote}

\subsection{What it loads}

\pkg{arabdoc-setup} automatically loads: \pkg{bidi}, \pkg{fontspec}, \pkg{polyglossia}, \pkg{hyperref}, \pkg{array}, \pkg{booktabs}, \pkg{tabularx}, \pkg{enumitem}, \pkg{float}, \pkg{titlesec}, \pkg{fancyhdr}, \pkg{setspace}, \pkg{xcolor}.

\section{arabdoc}

Document classes that auto-load \pkg{arabdoc-setup} with sensible defaults.

\subsection{Classes}

\begin{longtable}{ll}
\toprule
\textbf{Class} & \textbf{Base class} \\
\midrule
\pkg{arabdoc-article} & article \\
\pkg{arabdoc-book} & book \\
\pkg{arabdoc-report} & report \\
