		The Hurd Boxes and Arrows logo.

		Converted to SVG by Thomas Schwinge and Colin Leitner at 09/2007.
		We used the metafont original from Stephen McCamant (1997).
		available on http://www.gnu.org/graphics/hurd_mf.html.

		TODO.  The flection of some of the curves is different from the
		original.  We don't know yet how to exactly reproduce
		METAFONT's ``A..B'' syntax.  Also the thickness of the lines
		may be a different one.  Elaborate on the copyright situation
		and licensing conditions.
