+@acronym{SVG, Scalable Vector Graphics} output.  SVG with embedded media is
+very portable, as it is supported by all modern Web browsers across a variety
+of operating systems and platforms, including portable devices.  All DVI
+producing TeX engines can be used.  The @command{dvisvgm} utility converts the
+intermediate DVI to SVG.  By default, media files are embedded into the SVG
+output to make self-sufficient SVG files.")
