I have merged testing a single mirror into rankmirrors. Testing a mirror file is still the same usage. To test a mirror just do: rankmirrors -u ftp://archlinux.puzzle.ch/current/os/i686 or rankmirrors --url ftp://archlinux.puzzle.ch/current/os/i686 I also added a test to make sure the mirror filename provided actually exists. The patch is below. ~ Jamie / yankees26
