Axel tries to accelerate HTTP/FTP downloading process by using multiple connections for one file. It can use multiple mirrors for a download. Axel has no dependencies and is lightweight, so it might be useful as a wget clone on byte-critical systems.
It really makes a big difference when downloading large files from http/ftp servers. You can set multiple connections (default is 4) which speeds up download considerably. And what more, it is CLI based, is really small, and has no dependencies! :hap2:

Debian/Ubuntu users can install it by typing "sudo apt-get install axel" at the command line.
Edit : Just downloaded a 37mb file from a fast server. It maxed out at 45.11 KBps as opposed to 42.3 using wget/free download manager.
