I answered this question quite some time ago with a link that was useful to the asker at the time, but has since decayed (error 404). At the time, my answer was accepted, but it is now completely useless. Korvin's answer is still valid. I have flagged the answer.
Should I be able to delete my (now useless) answer, even though at the time it was accepted? Even if flagging it will lead to its deletion, surely that is a waste of moderators' time?
I am fully aware of the dangers of link-only answers, and was at the time; I merely sought to be of use to the asker with their immediate problem.
