-\ProvidesPackage{sphinxlatexgraphics}[2024/08/13 v8.1.0 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.
