\title{Critical notes}
\maketitle
\begin{abstract}
This file provides examples of critical notes with reledmac. 
A critical note is associated to a lemma, marked by \verb+\edtext+, and referenced by the line numbers of the lemma.
If a critical notes refers to a long lemma, we can use \verb+lemma+ to obtain an abbreviated form.

Here we use four series of critical notes. 
\begin{itemize}
\item Each note of series A has its own paragraph. 
\item Each note of series B has its own paragraph, but there are arranged in two columns.  
\item Each note of series C has its own paragraph, but there are arranged in three columns. 
\item The notes of series D are arranged in the same paragraph.
\end{itemize}
