		Nvidia provides different branches of its drivers for different batches of its
		hardware. When maintaining these ebuilds or other ebuilds depending on them,
		you will need to keep in mind that the major versions represent these different
		branches.

		You can use http://www.nvidia.com/Download/Find.aspx to figure out which branch
		best matches your hardware.
