Segmenting disc images

I had  a large Mac OSX disc image which needed to make it onto a few DVDs to be given away. Looking around I discovered a couple of downloadable utilities, but scratching a bit deeper I found the lovely hdiutil which has all the functionality I needed on the command line ...

hdiutil segment -segmentSize 4g -o outputPrefix largeDiscImage.dmg

Thanks Apple.
