sa-update also uses a mirror file which lists all of the URLs where the

mirrors.
But there's no documentation or examples given for weighting. Anyone
closer to the code know what this would look like?
$ curl http://spamassassin.apache.org/updates/MIRRORED.BY
http://sa-update.dnswl.org/ weight=1
http://www.sa-update.pccc.com/ weight=5
http://sa-update.secnap.net/ weight=5
sa-update has the following in its comments:
# choose a random integer between 0 and the total weight of all mirrors
# loop through the mirrors from largest to smallest weight
# if random number is < largest weight, use it
# otherwise, random number -= largest, remove mirror from list, try again
# eventually, there'll just be 1 mirror left in $mirrors[0] and it'll be used

sub choose_mirror {
my($mirror_list) = @_;
[...]
I'll add this on to the wiki.
