+%% NUMBERING OF FIGURES, TABLES, AND LITERAL BLOCKS

+\ProvidesFile{sphinxlatexnumfig.sty}[2021/01/27 numbering]

+% Requires: remreset (old LaTeX only)
+% relates to numfig and numfig_secnum_depth configuration variables

+% Everything is delayed to \begin{document} to allow hyperref patches into
+%   \newcounter to solve duplicate label problems for internal hyperlinks to
+%   code listings (literalblock counter).  User or extension re-definitions of
+%   \theliteralblock, et al., thus have also to be delayed. (changed at 3.5.0)

+% If document uses \part, (triggered in Sphinx by latex_toplevel_sectioning)
+% LaTeX core per default does not reset chapter or section
+% counters at each part.
+% But if we modify this, we need to redefine \thechapter, \thesection to
+% include the part number and this will cause problems in table of contents
+% because of too wide numbering. Simplest is to do nothing.
