Blame
Graphical git blame
It took me some time to find a powerful git blame interface. In fact the integrated git gui is a very effective tool and has an interesting blame view, capable of following commits by clicking on them and also following renamed / moved files.
Just start blaming a file with:
git gui blame path/to/file.src
Install on Arch Linux
This git gui is an optional dependcy of the git package on Arch Linux. You can install it with:
pacman -S tk
