+%% a stub for obsoleted LaTeX package substitutefont
+% The package substitutefont stopped being distributed with TeXLive
+% around August 2023 and was moved to "obsolete" section.
+% cf https://ctan.org/pkg/substitutefont
+% Trying to load it raises a LaTeX build error since.
+
+% The \substitutefont has a LaTeX kernel replacement
+%     \DeclareFontFamilySubstitution
+% which was added to LaTeX 2020-02-02
+% The aim of this stub is to do that replacement silently.
