# 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
# taskenizer.crabdance.com is run by Xylon. the others come from https://github.com/ngosang/trackerslist
trackers='http://taskenizer.crabdance.com:6969/announce,http://tracker.opentrackr.org:1337/announce,udp://tracker.pirateparty.gr:6969/announce'

# 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.
