Pachorizon - Sort your pacman mirrorlist by distance

Question

I'm behind a stupid firewall, and can't use ping, so can't use tools like rankmirrors.  So I wrote a python script for sorting mirrors with nearest countries.
Usage:
Usage: pachorizon.py <country> <mirrorlist>
pachorizon.py list
pachorizon.py help
Example: pachorizon.py "Great Britain" /etc/pacman.d/mirrorlist
Example output:
$ ./pachorizon.py "Great Britain" /etc/pacman.d/mirrorlist
## Pacman mirrorlist generated for Great Britain
## Great Britain
# Server = http://mirror.lividpenguin.com/pub/archlinux/$repo/os/$arch
# Server = http://mirror.cinosure.com/archlinux/$repo/os/$arch
# Server = http://archlinux.mirrors.uk2.net/$repo/os/$arch
## Ireland
# Server = http://ftp.heanet.ie/mirrors/ftp.archlinux.org/$repo/os/$arch
## Netherlands
# Server = http://mirror.nl.leaseweb.net/archlinux/$repo/os/$arch
# Server = http://ftp.nluug.nl/pub/os/Linux/distr/archlinux/$repo/os/$arch
## Belgium
# Server = http://archlinux.mirror.kangaroot.net/$repo/os/$arch
## Luxembourg
# Server = http://archlinux.mirror.root.lu/$repo/os/$arch

The wiki has https://wiki.archlinux.org/index.php/Mi … _Generator Maybe you can enhance that script?
If you're not sure if the outcome is correct, post it on the wiki talk page first.
