aria2 download tool

I ran into an interesting downloading application, Aria2. I was reminded of a GetRight utility I ran into years ago. The thing I really liked about GetRight at the time was the ability to download linux ISOs from multiple mirrors and merge the results into one coherent file. It really sped up downloading new Slackware releases :-) This to me is the most compelling feature of Aria2 and it works thus:

aria2c -s2 http://host/image.iso http://mirror1/image.iso http://mirror2/image.iso

The main page has plenty of examples with many different transfer protocols. Too bad the parallel download features seem to have disappeared with the invention of bit torrent.
