How to insert a triple line integral?

Question

A formula I want to typeset contains a tripple line integral, i.e. a symbol that has three integral signs that are encircled. How can I do this?

I tried \oiiint, but that does not work. \iiint works on the contrary.

Have a look at “How to look up a math symbol?” for ideas how you can easily find a particular symbol. However, I can't find it myself using Detexify, but my mouse-drawing skills might be just to bad :-) — Martin Scharrer, Mar 14 '11 at 17:28
@Martin: At the symbols link you can find out that the symbol isn't supported by Detexify, but you can send an e-mail to Daniel Kirsch. — Hendrik Vogt, Mar 14 '11 at 17:34
@Hendrik: Thanks, it seems that it doesn't support the whole mathdesign package yet. — Martin Scharrer, Mar 14 '11 at 17:39

The mathdesign package defines \oiiint, as do txfonts and pxfonts packages, according to the comprehensive symbols list.
