	\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|\cyrb|, \verb|\cyrg|, \verb|\cyrd|, \verb|\cyrp| and \verb|\cyrt|. 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 T1, TS1, T2A, X2 and OT2 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.

	\section{OT2 Features}
	
	The 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 OT2 encoding Macedonian letters Ѓ and Ќ are added, with Montenegrin letters \CYRSJE{} and \CYRZJE.
	
	However, it is not recommended to use the OT2 encoding; better choice for Serbian language is T2A encoding and utf8 input. One can use OT2 encoding if they already have a document written in Latin---in which case it would be easy to transcribe it to Cyrillic.
