DESCRIPTION
       This manual page documents briefly the btdownloadheadless,
       btdownloadcurses, and btdownloadgui commands.  This manual page was
       written for the Debian distribution because the original program does
       not have a manual page.

       These are all programs that allow a user to download files using
       bittorrent, a peer to peer, scatter-gather network protocol.  They all
       have the same options.

OPTIONS
       These programs follow the usual GNU command line syntax, with long
       options starting with two dashes (`-').  A summary of options is
       included below.

       --responsefile filename
              treat filename as a file which the server reponse was stored in.
              If this option is used, no filename or URL should be present on
              the command line.

       --url url
              retrieve the torrent info file from url.  If this option is
              used, no filename or URL should be present on the command line.

       -i ip | --ip ip
              report ip as your IP to the tracker

       --bind ip
              bind to ip instead of the default

       --minport portnum
              set portnum as the minimum port to listen on, counts up if
              unavailable (default 6881)

       --maxport portnum
              set portnum as the maximum port to listen on (default 6889)

       --saveas filename
              store the downloaded file to filename, instead of querying user
              (gui) or using the filename stored in the torrent info file

       --max_uploads num
              Only allow num uploads at once (default 4)

       --max_upload_rate kbytes
              maximum rate to upload at in kilobytes, 0 means no limit
              (default 0)

       --keepalive_interval secs
              pause secs seconds between sending keepalives (default 120.0)

       --download_slice_size bytes

       --request_backlog num
              keep num requests in a single pipe at once (default 5)

       --max_message_length bytes
              set bytes to the maximum length prefix encoding you'll accept
              over the wire - larger values get the connection dropped
              (default 8388608)

       --timeout secs
              wait secs before closing sockets which nothing has been recieved
              on (default 300.0)

       --timeout_check_interval secs
              check whether connections have timed out every secs seconds
              (default 60.0)

       --max_slice_length bytes
              requests from peers larger than bytes bytes are ignored (default
              131072)

       --max_rate_recalculate_interval secs
              connections that pause longer than secs seconds are given
              reduced rate (default 15.0)

       --max_rate_period secs
              set secs to the maximum amount of time to guess the current rate
              estimate represents (default 20.0)

       --upload_rate_fudge secs

       --rerequest_interval secs
              request more peers every secs seconds (default 300)

       --min_peers num
              do not rerequest if we have num peers already (default 20)

       --http_timeout secs
              wait secs seconds before assuming a http connection has timed
              out (default 60)

       --snub_time secs

       --spew  1 | 0
              whether to display diagnostic info to stdout.  This option is
              not useful when using btdownloadcurses or btdownloadgui.

       --report_hash_failures  1 | 0
              whether to report to the user that hash failuers occur (non-
              fatal, common error) (default 0)

       --rarest_first_priority_cutoff num
              the number of peers which need to have a piece before other
