\section{Introduction}
\subsection{About \texttt{bangla} Package}
The \texttt{bangla} package is a programming tool geared primarily towards LaTeX document authors. It provides all necessary LaTeX frontends for Bangla language.
\subsection{Licence}
Copyright © 2021 Nahid Hossain. Permission is granted to copy, distribute and/or modify this software under the terms of the LaTeX Project Public License, version 1.3c or later.
\section{Commands}
\subsection{Use Package}
The basic command to use the package is-\\ \\
\com{usepackage}{\{bangla\}}
\subsection{Font Selection}
\textbf{The default font of the \texttt{bangla} package is \texttt{Kalpurush}. If you do not mention any font name in the parameter, the Kalpurush will be your default font.} However, an author can easily change the font using the parameter of the \texttt{usepackage} command.
\\ \\
\com{usepackage}{[<font name>]\{bangla\}}
\\
For example, if an author wants \texttt{Noto Serif Bengali} as the font for the whole article, he can write-
\\ \\
\com{usepackage}{[notoserifbengali]\{bangla\}}
\\
The following SIL Open Font Licence(OFL) Bangla fonts are currently associated with the \texttt{bangla} package-
\begin{table}[H]
\centering
\begin{tabular}{|c|c|c|}
\hline
\textbf{Font Name} & \textbf{Command Keyword} & \textbf{Licence} \\
\hline
Kalpurush & \textcolor{blue}{\texttt{kalpurush}} & SIL OFL\\
\hline
Shimanto & \textcolor{blue}{\texttt{shimanto}} & SIL OFL \\
\hline
Noto Sans Bengali & \textcolor{blue}{\texttt{notosansbengali}} & SIL OFL\\
\hline
Noto Serif Bengali & \textcolor{blue}{\texttt{notoserifbengali}} & SIL OFL\\
\hline
\end{tabular}
\end{table}
\subsection{With Parameter Definitions}
In this subsection, we have demonstrated the commands that requires parameters(at least one or more).
\subsubsection{\com{banglatext}{\{<bangla text here>\}}}
\texttt{banglatext} displays any Bangla texts provided inside the parameter. Insert Bangla text in the parameter.\\
\begin{table}[H]
\centering
\begin{tabular}{|c|c|}
\hline
\textbf{Command} & \textbf{Output} \\
\hline
\texttt{\com{banglatext}{\{\banglatext{আমি বাংলায় কথা বলি।}\}}} & \banglatext{আমি বাংলায় কথা বলি।}\\
\hline
\end{tabular}
\end{table}
\subsubsection{\com{banglabold}{\{<bangla text here>\}}}
\texttt{banglabold} bolds the Bangla texts provided inside the parameter. It can make texts bold automatically of any font that has no bold fonts available.\\
\begin{table}[H]
\centering
\begin{tabular}{|c|c|}
\hline
\textbf{Command} & \textbf{Output} \\
\hline
\texttt{\com{banglabold}{\{\banglatext{আমি বাংলায় কথা বলি।}\}}} & \banglabold{আমি বাংলায় কথা বলি।}\\
\hline
\end{tabular}
\end{table}
\subsubsection{\com{banglaitalic}{\{<bangla text here>\}}}
\texttt{banglaitalic} makes the Bangla texts italic provided inside the parameter. It can make texts italic automatically of any font that has no italic fonts available.\\
\begin{table}[H]
\centering
\begin{tabular}{|c|c|}
\hline
\textbf{Command} & \textbf{Output} \\
\hline
\texttt{\com{banglaitalic}{\{\banglatext{আমি বাংলায় কথা বলি।}\}}} & \banglaitalic{আমি বাংলায় কথা বলি।}\\
\hline
\end{tabular}
\end{table}
\subsubsection{\com{banglatranslit}{\{<bangla text here>\}}}
\texttt{banglatranslit} generates a comprehensive and sophisticated transliteration of Bangla into Latin based on ISO 15919. \texttt{banglatranslit} works on character, word, and sentences as well.\\
\begin{table}[H]
\centering
\begin{tabular}{|c|c|}
\hline
\textbf{Command} & \textbf{Output} \\
\hline
\texttt{\com{banglatranslit}{\{\banglatext{আমি বাংলায় কথা বলি।}\}}} & \banglatranslit{আমি বাংলায় কথা বলি।}\\
