Options:
 --max-overall-download-limit=SPEED Set max overall download speed in bytes/sec.
                              0 means unrestricted.
                              You can append K or M(1K = 1024, 1M = 1024K).
                              To limit the download speed per download, use
                              --max-download-limit option.

 --max-download-limit=SPEED   Set max download speed per each download in
                              bytes/sec. 0 means unrestricted.
                              You can append K or M(1K = 1024, 1M = 1024K).
                              To limit the overall download speed, use
                              --max-overall-download-limit option.

 -V, --check-integrity[=true|false] Check file integrity by validating piece
                              hashes or a hash of entire file. This option has
                              effect only in BitTorrent, Metalink downloads
                              with checksums or HTTP(S)/FTP downloads with
                              --checksum option. If piece hashes are provided,
                              this option can detect damaged portions of a file
                              and re-download them. If a hash of entire file is
                              provided, hash check is only done when file has
                              been already download. This is determined by file
                              length. If hash check fails, file is
                              re-downloaded from scratch. If both piece hashes
                              and a hash of entire file are provided, only
                              piece hashes are used.

                              whose suffix is .torrent or content type is
                              application/x-bittorrent is downloaded, aria2
                              parses it as a torrent file and downloads files
                              mentioned in it.
                              If mem is specified, a torrent file is not
                              written to the disk, but is just kept in memory.
                              If false is specified, the .torrent file is
                              downloaded to the disk, but is not parsed as a

                              Possible Values: true, false
                              Default: false
                              Tags: #bittorrent


 --bt-request-peer-speed-limit=SPEED If the whole download speed of every
                              torrent is lower than SPEED, aria2 temporarily
                              increases the number of peers to try for more
                              download speed. Configuring this option with your
                              preferred download speed can increase your
                              download speed in some cases.
                              You can append K or M(1K = 1024, 1M = 1024K).


                              Possible Values: 0-*
                              Default: 50K
                              Tags: #bittorrent

                              verifying piece hashes.


                              Possible Values: true, false
                              Default: false
                              Tags: #bittorrent


 --bt-hash-check-seed[=true|false] If true is given, after hash check using
                              --check-integrity option and file is complete,
                              continue to seed file. If you want to check file
                              and download it only when it is damaged or
                              incomplete, set this option to false.
                              This option has effect only on BitTorrent
                              download.


                              Possible Values: true, false

 --bt-external-ip=IPADDRESS   Specify the external IP address to use in
                              BitTorrent download and DHT. It may be sent to
                              BitTorrent tracker. For DHT, this option should
                              be set to report that local node is downloading
                              a particular torrent. This is critical to use
                              DHT in a private network. Although this function
                              is named 'external', it can accept any kind of IP
                              addresses.


                              Possible Values: a numeric IP address

                              Tags: #bittorrent


 --bt-tracker-interval=SEC    Set the interval in seconds between tracker
                              requests. This completely overrides interval value
                              and aria2 just uses this value and ignores the
                              min interval and interval value in the response of
                              tracker. If 0 is set, aria2 determines interval
                              based on the response of tracker and the download
                              progress.


                              Possible Values: 0-*
                              Default: 0

 --bt-stop-timeout=SEC        Stop BitTorrent download if download speed is 0 in
                              consecutive SEC seconds. If 0 is given, this
                              feature is disabled.

 --bt-prioritize-piece=head[=SIZE],tail[=SIZE] Try to download first and last
                              pieces of each file first. This is useful for
                              previewing files. The argument can contain 2
                              keywords:head and tail. To include both keywords,
                              they must be separated by comma. These keywords
                              can take one parameter, SIZE. For example, if
                              head=SIZE is specified, pieces in the range of
                              first SIZE bytes of each file get higher priority.
                              tail=SIZE means the range of last SIZE bytes of
                              each file. SIZE can include K or M(1K = 1024, 1M =
                              1024K). If SIZE is omitted, SIZE=1M is used.


                              Possible Values: head[=SIZE], tail[=SIZE]

                              select files, use --select-file option. If
                              it is not used, all files are assumed to be
                              selected. Please use this option with care
                              because it will actually remove files from
                              your disk.


                              Possible Values: true, false
                              Default: false

 --bt-detach-seed-only[=true|false]
                              Exclude seed only downloads when counting
                              concurrent active downloads (See -j option).
                              This means that if -j3 is given and this option
                              is turned on and 3 downloads are active and one
                              of those enters seed mode, then it is excluded
                              from active download count (thus it becomes 2),
                              and the next download waiting in queue gets
                              started. But be aware that seeding item is still
                              recognized as active download in RPC method.


                              Possible Values: true, false
                              Default: false

 --bt-force-encryption[=true|false]
                              Requires BitTorrent message payload encryption
                              with arc4. This is a shorthand of
                              --bt-require-crypto --bt-min-crypto-level=arc4.
                              If true is given, deny legacy BitTorrent
                              handshake and only use Obfuscation handshake and
                              always encrypt message payload.


                              Possible Values: true, false
                              Default: false

 --bt-enable-hook-after-hash-check[=true|false] Allow hook command invocation
                              after hash check (see -V option) in BitTorrent
                              download. By default, when hash check succeeds,
                              the command given by --on-bt-download-complete
                              is executed. To disable this action, give false
                              to this option.


                              Possible Values: true, false
                              Default: true
