To be more clear: The customers will have their sources in their repository and we will have our sources in our repository. Updates shall be delivered to the customer by sending patches. So, the customers shall use Tortoise to apply the patches into their repository.

Allright. But at least it could not completely fail, if no historical data (no data of the standard source) is available and one hunk only fails.

I see your point. Do you know of any visual patch tool, meaning the commandline patch with a GUI?
Thanks!
