>From the description in the developer documentation: GetRequires: If recursive is true: This means if gnome-power-manager depends on NetworkManager and NetworkManager depends on HAL, then GetRequires on HAL should return both gnome-power-manager and NetworkManager. GetDepends: If recursive is true: This means if gnome-power-manager depends on NetworkManager and NetworkManager depends on HAL, then GetDepends on gnome-power-manager should return both HAL and NetworkManager. Why does this belong in the backends? Well, I tried doing this with lots of recursive calls to GetRequires(package_id) and for gimp it took a long time, when in yum took a few seconds. The backend doesn't have to do all this IPC, and so can do it much quicker. If your backend can't do a recursive GetDepends or GetRequires, just ignore the flag; anything is better than nothing.
