Mktorrent is a text-based utility to create BitTorrent metainfo files used by trackers and torrent clients. It can create metainfo files for single files or complete directories in a fast way.

It supports: - multiple trackers, - embedding custom comments into torrent files, - multi-threaded hashing.

It also supports setting the "private" flag, which advises the BitTorrent agents to refrain from using alternative peer discovery mechanisms, such as Distributed Hash Table (DHT), Local Peer Discovery (LPD), or Peer Exchange.
