+This creates the following files in `out/`:

+- `map.svg` is the map as a SVG image, with clickable links.
+- `map.png` is the map as a PNG image.
+- `imagemap.html` includes map.png, along with a HTML image map that makes the dots and labels clickable.
+- `erfamap.html` includes map.svg, with map.png and an imagemap as fallback.
+- `style/` contains the stylesheet and font.
 
 **If the wrong font is used in the PNG, make sure the chosen font is installed on your system.** ([CairoSVG](https://cairosvg.org/) does not support the use of `@font-face` in style sheets.)
