+% \paragraph{Single-layer apparatus} The following commands are for
+% general settings. All of them can be used in the preamble or at any
+% point of the document:---
+% \begin{macro}{\SetLTRapp}
+% \begin{macro}{\SetRTLapp}
+% \cs{SetLTRapp} and \cs{SetRTLapp} are two argument-less commands to
+% set the direction of single-layer apparatus criticus, either LTR or
+% RTL:---

+% \end{macro}
+% \begin{macro}{\SetSeparator}
+% \cs{SetSeparator}\marg{separator} allows to change the separator
+% between lemma texts and variant readings, which is by default
+% a closing square bracket followed by a space (\verb*+] +):---

 \edef\ekdsep{] }

+%    \end{macrocode}
+% \end{macro}
+% \begin{macro}{\SetEndApparatus}
+% \cs{SetEndApparatus}\marg{characters} can be used to append
+% characters at the end of the apparatus block\---such as a full stop,
+% as it is customary in some editions. By default, nothing is
+% appended:---
+%    \begin{macrocode}

+%    \end{macrocode}
+% \end{macro}
+% \begin{macro}{\SetUnitDelimiter}
+% \cs{SetUnitDelimiter}\marg{delimiter} can be used to set the
+% delimiter between entries in the apparatus criticus. By default,
+% there is no delimiter except a simple space. \cs{SetUnitDelimiter}
+% can be used to insert a broad space (with |\hskip| for instance, as
+% in the OCT series) or the divider-sign (‖, as in the Budé series):---
