2. About aria2
--------------
aria2 has segmented downloading engine in its core. By segmented downloading,
it can download files very much faster than ordinary browsers.
Introduction
------------
aria2 is a utility for downloading files. The supported protocols are HTTP(S), FTP, BitTorrent, and Metalink. It has a powerful segmented downloading ability, downloading a file from multiple sources and multiple protocols and utilizing your download bandwidth to the maximum. It supports downloading a file from HTTP(S)/FTP and BitTorrent at the same time, while the data downloaded from HTTP(S)/FTP is uploaded to the BitTorrent swarm. Using Metalink's chunk checksums, aria2 automatically validates chunks of data while downloading a file like BitTorrent.
Here is a list of features.
aria2 is in very early development stage. Currently it has following features:
* HTTP/HTTPS GET support
* HTTP Proxy support
* HTTP BASIC authentication support
* HTTP Proxy authentication support
* FTP support(active, passive mode)
* FTP through HTTP proxy(GET command or tunneling)
* Segmented download
* Multi-source/segmented downloading ability
* Cookie support
* It can load cookies from file whose format is used by Netscape and Mozilla.
* It can run as a daemon process.
* BitTorrent protocol support with fast extension.
* BitTorrent protocol support with fast extension, DHT, encryption, PEX enabled.
* Selective download in multi-file torrent/metalink.
* Metalink version 3.0 support(HTTP/FTP/BitTorrent).
* Limits download/upload speed.

different sources.
3. Dependency
-------------
In order to enable HTTPS support, you need GNU TLS or OpenSSL.
In order to enable BitTorrent support, you need GNU TLS+libgcrypt or OpenSSL.
In order to enable Metalink support, you need libxml2 or Expat. Optionally
GNU TLS+libgcrypt or OpenSSL are required for checksum checking support(MD5,
SHA1, SHA256).

How to build
------------
In order to build aria2 from the source package, you need following development
packages(package name may vary depending on the distribution you use):
* libgnutls-dev (Required for HTTPS, BitTorrent support)
* libgpg-error-dev (Required for BitTorrent support)
* libgcrypt-dev (Required for BitTorrent support)
* libgnutls-dev (Required for HTTPS, BitTorrent, Checksum support)
* libgpg-error-dev (Required for BitTorrent, Checksum support)
* libgcrypt-dev (Required for BitTorrent, Checksum support)
* libares-dev (Required for async DNS support)
* libxml2-dev (Required for Metalink support)
You can use libssl-dev instead of libgnutls-dev,libgpg-error-dev,libgcrypt-dev:
* libssl-dev (Required for HTTPS, BitTorrent support)
* libssl-dev (Required for HTTPS, BitTorrent, Checksum support)
You can use libexpat1-dev instead of libxml2-dev:
* libexpat1-dev (Required for Metalink support)
The build process is fairly standard way for *nix programs:

$ ./configure
$ make

The executable is aria2c in src directory.

Note:
* -o option is used to change the filename of downloaded .torrent file.
* The ports aria2c uses are 6881-6999.
DHT
~~~
As of release 0.13.0, aria2 supports DHT. The routing table is saved to $HOME/.aria2/dht.dat.
Note;;
* -o option is used to change the filename of .torrent file itself, not a filename of a file in .torrent file.

* The maximum number of peers is 55. This limit may be exceeded when download
rate is low.
* As of release 0.10.0, aria2 stops sending request message after selective
