+\section{Introduction}
+Including any unicode text in \hologo{LaTeX} has become very simple thanks to the \hologo{XeLaTeX} engine. To do so, the user only has to use the {\tt fontspec} package and load an appropriate font. This is the standard technique for including multiple languages in one document. The {\tt polyglossia} package even facilitates the process for many languages by providing refined controls. Unfortunately, {\tt polyglossia}'s support for Bangla is too limited to produce good quality Bangla documents.
+
+So, I decided to address all the common Bangla typesetting problems in this package, \latexbangla. I have also added useful functionalities to it such as, automated transition between Bangla and English (by exploiting \hologo{XeTeX}'s internal character class feature) and many more.
+\section{How to use}
+\subsection{Sample Code}
+Here is the simplest example for \latexbangla:
+\begin{tcolorbox}[breakable]
+\begin{verbatim}
+\documentclass{article}
+\usepackage[banglamainfont=Kalpurush,
+ banglattfont=Siyam Rupali
+ ]{latexbangla}
+\begin{document}
+পিথাগোরাস(Pythagoras)-এর উপপাদ্যটি হল,\\
+\textit{সমকোণী ত্রিভুজের অতিভুজের উপর অঙ্কিত বর্গক্ষেত্রের ক্ষেত্রফল অপর দুই বাহুর
+উপর অঙ্কিত বর্গক্ষেত্রের ক্ষেত্রফলের সমষ্টির সমান।}\\
+অর্থাৎ কোন সমকোণী ত্রিভুজের অতিভুজ $c$ এবং অপর দুই বাহু $a$ এবং $b$ হলে,
+\[c^2=a^2+b^2\]
+লক্ষ্য করুন, এখন পর্যন্ত টেক্সট প্রদর্শনের জন্য \textbf{কালপুরুষ} ফন্ট ব্যবহৃত হয়েছে।\\
+\texttt{এবার, টেলিটাইপ(Teletype) টেক্সট প্রদর্শনের জন্য \textbf{সিয়াম রূপালী}
+ফন্ট ব্যবহৃত হল।}\\
+পুনরায় টেক্সট প্রদর্শনের জন্য \textbf{কালপুরুষ} ফন্ট ব্যবহৃত হচ্ছে।
+\end{document}
+\end{verbatim}
+\end{tcolorbox}
+\begin{tcolorbox}[breakable, colback=white]
+পিথাগোরাস(Pythagoras)-এর উপপাদ্যটি হল,\\
+\textit{সমকোণী ত্রিভুজের অতিভুজের উপর অঙ্কিত বর্গক্ষেত্রের ক্ষেত্রফল অপর দুই বাহুর
+উপর অঙ্কিত বর্গক্ষেত্রের ক্ষেত্রফলের সমষ্টির সমান।}\\
+অর্থাৎ কোন সমকোণী ত্রিভুজের অতিভুজ $c$ এবং অপর দুই বাহু $a$ এবং $b$ হলে,
+\[c^2=a^2+b^2\]
+লক্ষ্য করুন, এখন পর্যন্ত টেক্সট প্রদর্শনের জন্য \textbf{কালপুরুষ} ফন্ট ব্যবহৃত হয়েছে।\\
+\texttt{এবার, টেলিটাইপ(Teletype) টেক্সট প্রদর্শনের জন্য \textbf{সিয়াম রূপালী}
+ফন্ট ব্যবহৃত হল।}\\
+পুনরায় টেক্সট প্রদর্শনের জন্য \textbf{কালপুরুষ} ফন্ট ব্যবহৃত হচ্ছে।
+\end{tcolorbox}
+As you see, no special command was required to switch language or to use any other facility. With \latexbangla, you don't need to learn a hundred new commands to type Bangla. You simply type normal \hologo{LaTeX} syntax and expect everything to work as it should.
+
+\latexbangla~does have some limitations, however. (Most of which are due to my lack of time to implement solutions.) So, do take a look at the known issues section.
+\section{Functionalities}
+\subsection{Package options}
+Package options are listed below:\vspace*{2mm}
+\begin{itemize}
+\renewcommand\labelitemi{}
+
+\item\noindent\texttt{banglamainfont}\textbf{(Required)}\\
+Sets the default Bangla font for the document, but does not affect the Latin characters. (They are rendered by the \hologo{LaTeX} default Latin Modern font.) \latexbangla~will automatically fake bold, italic and bolditalic variants for \pkn{banglamainfont} if no font from the appropriate subfamily is found.\\
+
+\item\texttt{banglattfont}\textbf{(Required)}\\
+The default Teletype Bangla font. (Again, Latin characters are rendered by the \hologo{LaTeX} default Latin Modern Teletype.) \latexbangla~will also fake bold, italic and bolditalic variants automatically for this font if no font from the appropriate subfamily is found.\\
+
+\item\texttt{feature}(Optional, default=1)(\texttt{0->none, 1->recommended, 2->full})\\
+To which extent \latexbangla~should enable additional features. For \pkn{feature=1}, the following features will be enabled:
+\begin{enumerate}
+\item the following packages are loaded: \pkn{titlesec, amsthm, xpatch, amsfonts, amssymb, amsmath, enumerate, chngcntr}.
+\item a ``Dot" is added after chapter, section, subsection etc. numbers.
+\item \textit{প্রমাণ.} is replaced by \textbf{প্রমাণ:} in \pkn{proof} environment.
+\item Line height is set to 110\%.
+\item A new command \verb|\tobangla{counter name}| is defined. (See commands subsection for description)
+\item \pkn{example, problem, solution, theorem} environments are defined. The counter associated with \texttt{theorem} environment resets in every section.
+\item The counters associated with \pkn{enumerate, footnote} environments are converted to Bangla.
+\end{enumerate}
+\begin{tcolorbox}[breakable]
+\begin{verbatim}
+\usepackage[banglamainfont=Kalpurush,
+ banglattfont=Siyam Rupali,
+ ]{latexbangla}
+\begin{document}
+\begin{problem}
+$p$ একটি মৌলিক সংখ্যা এবং $n$ একটি স্বাভাবিক সংখ্যা হলে প্রমাণ কর যে
+$p|n^p-n$
+\end{problem}
+\begin{proof}
+$p|n$ হলে এটি স্বাভাবিকভাবেই সত্যি। অন্যথায়, $\{n,2n,\ldots,(p-1)n\}$
+ একটি পূর্ণাঙ্গ রেসিডিও ক্লাস তৈরি করে। যার ফলে...
+\end{proof}
+\begin{problem}
+$a$ এবং $n$ পরস্পর সহমৌলিক স্বাভাবিক সংখ্যা হলে দেখাও যে $a^{\phi(n)}
+\equiv 1\pmod n$
+\end{problem}
+\end{document}
+\end{verbatim}
+\end{tcolorbox}
+\begin{tcolorbox}[breakable, colback=white]
+\begin{problem}
+$p$ একটি মৌলিক সংখ্যা এবং $n$ একটি স্বাভাবিক সংখ্যা হলে প্রমাণ কর যে $p|n^p-n$
+\end{problem}
+\begin{proof}
+$p|n$ হলে এটি স্বাভাবিকভাবেই সত্যি। অন্যথায়, $\{n,2n,\ldots,(p-1)n\}$ একটি
+পূর্ণাঙ্গ রেসিডিও ক্লাস তৈরি করে। যার ফলে...
+\end{proof}
+\begin{problem}
+$a$ এবং $n$ পরস্পর সহমৌলিক স্বাভাবিক সংখ্যা হলে দেখাও যে $a^{\phi(n)}\equiv 1\pmod n$
+\end{problem}
+\end{tcolorbox}
+
+If \pkn{feature} is set to 2, the following additional features will be enabled:
+\begin{enumerate}
+\item \texttt{corollary, property, hint, remarks} environments. The counters of \texttt{corollary} and \texttt{property} environment reset in every section. \pkn{hint} and \pkn{remarks} environments have no counter.
+\item Automated parentheses around equation references, activated by the \pkn{autoref} command of the \pkn{hyperref} package.
+\end{enumerate}
+\item\pkn{changecounternumbering}(Optional, default=1)\\
+The \pkn{polyglossia} package does have an option to convert some important counters (like those of chapters and sections) to Bangla. This option asks whether \latexbangla~should enable that option. By default, it is set to be enabled. You may consider disabling it if your document mostly contains English text.
+\end{itemize}
+\subsection{Commands}
+\begin{itemize}
+\renewcommand\labelitemi\relax
+\item\verb|\tobangla{counter name}|\\
+Converts a counter to Bangla.
+\begin{tcolorbox}[breakable]
+\begin{verbatim}
+\newcounter{test}
+A new counter `test' is defined.\\
+test is in English: \thetest\\
+\renewcommand{\thetest}{\tobangla{test}}
+test is now in Bangla: \thetest\\
+\stepcounter{test}
+Incrementing test: \thetest\\
+\renewcommand{\thetest}{\arabic{test}}
+test is again in English: \thetest
+\end{verbatim}
+\end{tcolorbox}
+\begin{tcolorbox}[breakable, colback=white]
+\newcounter{test}
+A new counter `test' is defined.\\
+test is in English: \thetest\\
+\renewcommand{\thetest}{\tobangla{test}}
+test is now in Bangla: \thetest\\
+\stepcounter{test}
+Incrementing test: \thetest\\
+\renewcommand{\thetest}{\arabic{test}}
+test is again in English: \thetest
+\end{tcolorbox}
+\item\verb|\numtobangla{number}|\\
+same as \verb|\tobangla|. It converts an English number to Bangla.
+\end{itemize}
+\section{Known Issues}
+You might face the following issues for this (v 0.1) release of \latexbangla. I hope to fix them in the upcoming releases. If you have any question or suggestion, don't hesitate to contact me.
+\begin{enumerate}
+\item You \textit{must} define both {\tt banglamainfont} and {\tt banglattfont} even if you use only one or (possibly) none of them in the document.
+\item A font can't be both {\tt banglamainfont} and {\tt banglattfont} due to limitation in the internal logics. Until I fix it, you can set Kalpurush and SolaimanLipi as your main and tt fonts since they look identical.
+\item The whitespace character in many Bangla fonts is too short for \hologo{LaTeX}. This can't be `fixed', since it is purely a font specific issue. Nevertheless, I have manually reset relative whitespace lengths for ``Kalpurush'', ``SolaimanLipi'' and ``Siyam Rupali'' (precisely these names without the quotes). So, for the best results, you should consider installing these fonts before using \latexbangla. (Other Bangla fonts \textit{will} work with \latexbangla, but their interword spacings might be unsatisfactory.) My personal choice for main/tt font combination is Kalpurush/Siyam Rupali.
+\item Package \texttt{listings} does not work with Teletype texts.
+\end{enumerate}
+\section{Implementation}
+Because this package depends on \pkn{ucharclasses} (which itself depends on XeTeX's \pkn{interchar classes}).
+\begin{tcolorbox}[breakable]
+\begin{verbatim}
+\RequirePackage{polyglossia, fontspec, xkeyval, ifxetex}
+\RequireXeTeX
+\end{verbatim}
+\end{tcolorbox}
+The following Bangla fonts are fully supported. (Other Bangla fonts \textit{are} supported, but some issues might arise with whitespaces.
