Command line tool to convert SVG to EMF (Enhanced Metafile)

If you want the exact command to do this here it is:

$ inkscape --file <Input-file> --export-emf <output-file>

Looks like you can use inkscape from the command lone to do this with the -M switch.

With Inkscape 1.0 the commands changed. And since this is the top Google result, I thought it might be worth to update the answer:

inkscape filename.svg --export-filename filename.emf
