rankmirrors and new mirrrorlist format

[Mathias Huber <huber@xxxxxxxxxxxxxxx>]

Dear Archers,

is it true that rankmirrors can't handle mirrorlist urls like 
ftp://ftp.halifax.rwth-aachen.de/archlinux/$repo/os/$arch?

While pacman works fine with this format, rankmirrors produces 
unreachable URLs.

Or am I misunderstanding something here?

Rock on,
Mathias
