# This script is called by `make_repo_torrents' to make a torrent. It
# depends on `mktorrent'. It takes the following args:
# $1 - path of package
# $2 - public location

# Comma seperated list of trackers, no spaces
# t67.eu is run by Xylon, hackcoop by fauno & friends

# This mirror is put as a webseed. Which mirror we use for a webseed
# doesn't really matter since it's re-written on the client machine by
# pacman2pacman so it won't normally be used anyway.
