SVG supported scripted

Hi all,

I have a old piece of code, which I think I got from Adobe for
performing a check to see if the browser supports SVG. It works ok for
IE, but it seems to assume that if its not IE then plugins need to be
checked. This to me doesn't seem to be valid anymore as some browsers
support SVG natively.

I have been googling to see If I can find a script that will determine
if SVG is suported for a browser, but no joy, cant find one. This is
how I imagine it would work, Returning true for for all browser and
versions that SVG is known to be supported on, checking for a plugin
on browsers that require a pluggin and returning true or false
depending on if its installed or not, and return false in all other
scenrios.

I would imagine this already exists, anybody know where I might find
this?

Thanks,
Dale
