moving local Mailboxes to Gmail IMAP

I was thinking of moving all of my Mailboxes and the corresponding emails into my Gmail IMAP account. Is there any sure way of sending them over or importing and keeping the same folder structure? I read that Gmail doesn't use folders, but labels. How might that work with the structure I want. I would like my Gmail account to reflect exactly what I have in all my local folders on my Mac.
