\title{Stanza with double line numbering}
\maketitle

\begin{abstract}
This file provides an example of typesetting verse with reledmac using a double line numbering system.

The new edition adds a starting line of verse not present in the previous one, so we need to make an addition within the margin and textsuperscript the numbering from the older edition. In the centre, we split what was in the first edition one line of verse into two.



To mark the old numbering, we use \verb+\linenumannotation+. For maximum clarity, all line numbers are shown thanks to the settings of \verb+\firstlinenum+ and \verb+\linenumincrement+ in the preamble.
