	\title{The \texttt{cmsrb} package}
	\author{Uroš Stefanović\footnote{\texttt{urostajms@gmail.com}}}
	\date{\today{} v4.0}
	\maketitle
	
	\section{Why \textsf{cmsrb}?}
	
	The \textsf{cm-super} package provides great support for Cyrillic script in various languages, but there's a problem with italic variants of some letters for Serbian and Macedonian. The \textsf{cmsrb} package includes the correct shapes for italic letters \verb|\cyrg|, \verb|\cyrd|, \verb|\cyrp|, \verb|\cyrt| and letter \verb|\cyrb|. This package also has some improvements in letters and accents used in Serbian language.
	
	\section{Package Features}
	
	The \textsf{cmsrb} fonts are the extensions of the Computer Modern fonts for Serbian and Macedonian languages for \TeX{} (\LaTeX). Support files are provided for \texttt{T1}, \texttt{TS1}, \texttt{T2A}, \texttt{X2} and \texttt{OT2} encodings, but also for the experimental \texttt{ECMSRB1} and \texttt{ECMSRB2} encodings. Supported font styles are serif, sans-serif and mono, for size 10pt.
	
	This package is very simple to use: just put
	\begin{verbatim}
	\usepackage{cmsrb}
	\end{verbatim}
	in preamble of the document.

		\caption{Some \textsf{cm-super} and \textsf{cmsrb} differences.}\label{t2}
	\end{table}
	
	\section{OT2 Features}
	
	The \texttt{OT2} encoding is modified to match the rules of Latin to Cyrillic transcription in Serbian language. Therefore, the \textsf{ts}, \textsf{kh}, \textsf{ch} and similar ligatures are removed from the encoding (see Table~\ref{t1}).
	
	In \texttt{OT2} encoding Macedonian letters {\fontencoding{T2A}\selectfont Ѓ} and {\fontencoding{T2A}\selectfont Ќ} are added, with Montenegrin letters {\fontencoding{T2A}\selectfont\CYRSJE} and {\fontencoding{T2A}\selectfont\CYRZJE}, and also some orthographic symbols are included.
	
	However, it is not recommended to use the \texttt{OT2} encoding; better choice for Serbian language is \texttt{T2A} encoding and utf8 input. One can use \texttt{OT2} encoding if they already have a document written in Latin---in which case it would be easy to transcribe it to Cyrillic.

	\section{T1 Features}

	The \texttt{T1} encoding now support conversion from Cyrillic to Latin script (see Example~\ref{prim:t1}).

	On the position 208 now is the letter Đ (\texttt{U+0110}) instead of the letter {\fontencoding{TS1}\selectfont \DH} (\texttt{U+00D0}), which enable copying and searching in the Serbian or Croatian Latin text.

	\section{T2A Features}
	
	The Cyrillic letters {\fontencoding{T2A}\selectfont\texttt{Ј}} and {\fontencoding{T2A}\selectfont\texttt{ј}} are not supported in the \texttt{T2A} encoding, so they are placed instead of the Latin letters \texttt{J} and \texttt{j}.
	This give us the better results in the Cyrillic text, but that also means this Latin letter are not present in the \texttt{T2A} encoding, so be carefull during searching and copying Latin text in this encoding.
	
	The letters {\fontencoding{X2}\selectfont \char"81, \char"89, \char"86, \char"91, \char"A1, \char"A9, \char"A6, \char"B1} are removed from the \texttt{T2A} encoding, and on their places now are the letters {\fontencoding{T2A}\selectfont \char"81, \char"89, \char"86, \char"91, \char"A1, \char"A9, \char"A6, \char"B1}.

\section{TS1 Features}

In the \texttt{TS1} encoding we can find the letter {\fontencoding{TS1}\selectfont \DH} (\texttt{U+00D0}), which is removed from the \texttt{T1} encoding.
Also, in the \texttt{TS1} encoding now are the letters {\fontencoding{T2A}\selectfont б, г, д, п, т} with Russian italic shape.

	\section{Math}
	
	The \textsf{cmsrb} package load default Computer Modern math fonts, but load only fonts with size lower or equal 10pt, for better visual effect.
	If the option \textsf{math} is used, then the package \textsf{cmupint} will be loaded, and the integral sign will be changed from $\enint$ to $\int$ (upright integral is traditionally used in Serbian language, with \verb|\limits| option).
	Also, in Serbian language is better to use the symbols $\leqslant$ and $\geqslant$ than the symbols $\leq$ и $\geq$. If the \textsf{math} option is used the package \textsf{amssymb} will be loaded and this symbols will be changed (also $\nleqslant$ and $\ngeqslant$ will be used).
	
	We use this option like this:
	\begin{verbatim}
	\usepackage[math]{cmsrb}
	\end{verbatim}
	
\begin{primer}
\documentclass{article}
\usepackage{cmsrb}
\newcommand{\ud}{\,\mathrm{d}}
\begin{document}
$$ \int_0^1 e^x\ud x \geq 0 $$
\end{document}
\end{primer}

\begin{rezultat}
$$ \enint\nolimits_0^1 e^x\,\mathrm{d} x \geq 0 $$
\end{rezultat}

\begin{primer}
\documentclass{article}
\usepackage[math]{cmsrb}
\newcommand{\ud}{\,\mathrm{d}}
\begin{document}
$$ \int_0^1 e^x\ud x \geq 0 $$
\end{document}
\end{primer}

\begin{rezultat}
$$ \int_0^1 e^x\,\mathrm{d} x \geqslant 0 $$
\end{rezultat}

	\section{Experimental encodings}

	The encodings \texttt{ECMSRB1} and \texttt{ECMSRB2} are created for this package only. They are similar to \texttt{OT2} encoding, but they contain specific ligatures and accents (see Table~\ref{t3}). For the complete list of characters used in this encodings see Tables on Pages~\pageref{ecs1} and \pageref{ecs2}. The purposes of this encodins are writting Serbian text using only \texttt{ASCII} characters, and making simple conversions from Latin to Cyrillic.
