     "mktorrent is a simple command-line utility to create BitTorrent
@dfn{metainfo} files, often known simply as @dfn{torrents}, from both single
files and whole directories.  It can add multiple trackers and web seed URLs,
and set the @code{private} flag to disallow advertisement through the
distributed hash table (@dfn{DHT}) and Peer Exchange.  Hashing is multi-threaded
and will take advantage of multiple processor cores where possible.")
