How do you do???

"How do you do?" not "How did you do?" not "How are you?"
Why is How-do-you-do, a form of greeting for humans meeting for the first time?
Do they mean "What're you doing?" "What's with your hair?" "Can you tell me how to do this?"
Such a funny string of small words.

But anyway,
How-do-you-do to you!
