====== Download using the aria2 download manager ======
===== Description =====
This is a simple script which downloads files using the aria2
download manager by sending URIs to an aria2 daemon.
Supported protocols are HTTP(S), FTP, BitTorrent and Metalink. 
Also uses cookies and can download a file from HTTP/FTP and BitTorrent
at the same time. Needs at least aria2 version 1.4.0 (with the XML-RPC 
interface) and the commandline utility 
[[http://sourceforge.net/apps/trac/aria2/attachment/wiki/XmlrpcInterface/aria2rpc|aria2rpc]].
You can then use tools like 
[[http://sourceforge.net/apps/trac/aria2/attachment/wiki/XmlrpcInterface/aria2mon|aria2mon]]
to check the status of your downloads in the command line, or write your
own utilities using the XML-RPC interface.
See also http://aria2.sourceforge.net/ for more information.
