Let's say I have repo A, the main branch. I clone repo A into repo B, in repo B I make changes to it over a period of time. Then I decide to clone repo A again into repo C, it has what repo A has plus changes that other users have made over time. Using TortoiseHg, how can I can combine repo B and C so I can push them into repo A?
Pardon me if my vocabulary isn't that good with the title or description, it's the best way I could describe it.
