How do I bulk download all attachments from all my emails in Gmail?

Hereward Dundas-Taylor asks:

Any bright spark can download attachments from a single email in Gmail, or a bunch one at a time, but how does one download all the attachments from all the complete history of emails in Gmail to their hard drive.

Has someone got the answer?
