[CentOS] nvidia-installer

CentOS 6.4

Came back from vacation, rebooted workstation, no X. Wound up running
nvidia-installer. Now, I had been using kmod-nvidia, but had to stop a
month or so ago, when NVidia stopped supporting my two-yr-old card
("legacy"). When that happened, I uninstalled kmod-nvidia.

One dumb question: I can't figure out where I got nvidia-installer. It
happily d/l the most current valid version with --update, which it tells
me (with --help) that it goes to ftp://download/nvidia.com. -v tells me
nvidia-installer:  version 319.23

Any clues?
