Summarise a Long Email Thread in Three Lines

The thread has forty replies, you have a meeting in ten minutes, and you have read none of it. Paste the chain and this pulls out the original request, any decisions made, and the open actions still hanging. Three lines instead of forty. For anyone walking into a meeting cold.
