From 953415c86a17c1db8bebbbaca89e6fd5783386b6 Mon Sep 17 00:00:00 2001 From: Dave Reisner Date: Sun, 22 Apr 2012 17:38:48 -0400 Subject: rankmirrors: move to contrib/ This script is of questionable value, as it ranks mirrors by an uninteresting attribute: ping. While the script itself is interesting, people should be encouraged to rank mirrors by more useful measures, such as actual speed, locality, or up to date-ness.
