DESCRIPTION

       This  manual  page  documents  briefly  the options available to the bittorrent-downloader
       commands.

       This manual page was written for the Debian distribution because the original program does
       not have a manual page.

       btdownloadheadless,  btdownloadcurses, btdownloadgui, btlaunchmany, and btlaunchmanycurses
       are all programs that allow a user to download files using bittorrent,  a  peer  to  peer,
       scatter-gather  network protocol. They all share a common set of options, shown below. For
       more information on how to  run  them,  and  their  program-specific  options,  see  their
       individual man pages.

OPTIONS

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

       --max_uploads number
                 the maximum number of uploads to allow at once (defaults to 7)

       --keepalive_interval seconds
                 the number of seconds to pause between sending keepalives (defaults to 120.0)

       --download_slice_size bytes
                 the number of bytes to query for per request (defaults to 16384)

       --upload_unit_size bytes
                 when limiting the upload rate, the number of bytes to send at a  time  (defaults
                 to 1460)

       --request_backlog number
                 the maximum number of requests to keep in a single pipe at once (defaults to 10)

       --max_message_length length
                 the  maximum  length prefix encoding you'll accept over the wire.  Larger values
                 will get the connection dropped. (defaults to 8388608)

       --ip ip   the ip to report you have to the tracker (defaults to '')

       --minport port
                 the minimum port to listen on (defaults to 10000)

                 the maximum port to listen on (defaults to 60000)

       --random_port 0|1
                 whether to choose randomly  inside  the  port  range  (instead  of  counting  up

       --responsefile file
                 the  file the server response was stored in, as an alternative to --url. If this
                 option is used, no filename or URL  should  be  present  on  the  command  line.
                 (defaults to '')

       --url URL the  URL  to  get the torrent file from, as an alternative to --responsefile. If
                 this option is used, no filename or URL should be present on the  command  line.

                 file/torrent order as shown by btshowmetainfo. For example, to download only the
