 <p><code>ekdosis</code> is a LuaLaTeX package designed for multilingual critical editions. It can be used to typeset texts and different layers of critical notes in any direction accepted by LuaTeX. Texts can be arranged in running paragraphs or on facing pages, in any number of columns which in turn can be synchronized or not. In addition to printed texts, <code>ekdosis</code> can convert <code>.tex</code> source files so as to produce <code>TEI xml</code>-compliant critical editions. Database-driven encoding under LaTeX then allows extraction of texts entered segment by segment according to various criteria: main edited text, variant readings, translations or annotated borrowings between texts. It is published under the terms of the GNU General Public License (GPL) version 3.</p>
