+%% GRAPHICS
+%
+% change this info string if making any custom modification
+\ProvidesFile{sphinxlatexgraphics.sty}[2021/01/27 graphics]
+
+% Provides support for this output mark-up from Sphinx latex writer:
+%
+% - macros:
+%
+%   - \sphinxfigcaption
+%   - \sphinxincludegraphics
+%
+% - environments:
+%
+%   - sphinxfigure-in-table
+%
+% May change:
+%
+% - \sphinxcaption (at begin document)
+%
+% Also provides:
+%
+% - \sphinxsafeincludegraphics (default of \sphinxincludegraphics since 2.0)
+% - \spx@image@maxheight dimension (used by sphinxlatexadmonitions.sty)
+% - \spx@image@box scratch box register (also used by sphinxlatexliterals.sty)
+%
+% Requires:
+% \RequirePackage{graphicx}% done in sphinx.sty
+\RequirePackage{amstext}% needed for \firstchoice@true(false)
+
+% \sphinxincludegraphics resizes images larger than the TeX \linewidth (which
+% is adjusted in indented environments), or taller than a certain maximal
+% height (usually \textheight and this is reduced in the environments which use
+% framed.sty to avoid infinite loop if image too tall).
+%
+% In case height or width options are present the rescaling is done
+% (since 2.0), in a way keeping the width:height ratio either native from
+% image or from the width and height options if both were present.
