% Include SVG graphics in LaTeX via Inkscape.
%
% This package defines two LaTeX commands `\includesvg' and `\includesvgpdf'.
%
% The command `\includesvg` imports an SVG file by separating its text from
% graphics, converting the graphics to a PDF and overlaying the text on the
% PDF using LaTeX. Inkscape is used for the conversion to PDF.
%
% The command `\includesvgpdf' imports an SVG file by converting it to PDF,
% including the text. Inkscape is used for the conversion to PDF.
%
% These commands require:
% - invoking LaTeX with the option `--shell-escape'.
% - Inkscape: https://inkscape.org
% - the Python package SVGLaTeX: https://github.com/johnyf/svglatex
