+%
+% Allow to suppress section numbering for some parts of the document
+% (e.g. in changelog entries).
+%
+% Sphinx employs the "titlesec" package to style its chapter and section
+% headings and uses its \titleformat command with a 0.5em separation
+% (see \titleformat calls in sphinxlatexstyleheadings.sty).
+% So make \the<section> output nothing (e.g. the section number)
+% but just a compensation for this whitespace.
+%
+% Each suppress command suppresses its level and all levels below
+% (compare with the \titleformat calls in sphinxlatexstyleheadings.sty).
+%
+% \EndSuppressNumbering ends exactly one preceding
+% \SuppressSubsectionNumbering or \SuppressSubsubsectionNumbering.
