This module provides an Perl-Interface towards the gnome-lib
librsvg\-2 which is able to convert \s-1SVG\s0(Scaleable Vector Graphics)
into bitmapformats like (\s-1PNG,JPG,...\s0). To which formats you can convert
the svg-files depends on your gdk-pixbuf configuration. Still at least
\&\s-1PNG\s0 and \s-1JPG\s0 should be available.
