+% \paragraph{Limiting the Number of Entries per Page}
+% In some instances, it can be useful to set a limit to the number of
+% entries per page that a given layer of critical notes may accept,
+% notably when entries are so abundant in number that \pkg{ekdosis}
+% may oscillate indefinitely between different sets of page decisions
+% without being able to settle down.\\
+% \DescribeOption{maxentries} |maxentries|=\meta{n} (where $n \geq
+% 10$) \hfill\tcboxverb{Default: not set}\\
+% If |maxentries|$=$\meta{n} be set, then \pkg{ekdosis} will issue
+% \cs{pagebreak} (namely \cs{penalty}|-10000|) just after the
+% \emph{n\textsuperscript{th}} entry has been inserted in the layer of
+% the apparatus criticus this option is related to. As a result, the
+% page will actually break at the end of the current line. The
+% particulars of this technique will be discussed below in
+% \vref{sec:tricks-of-trade}.
