What is a jigdo-file in linux?

What is a jigdo file? I came across this file while downloading Fedora Linux. Is it similar to torrent technology or something different! I'm too curious to know! So asked it on TA. i know i would be answered soon! Thanks in advance!

Jigdo stands for Jigsaw Download

Jigdo (short for "Jigsaw download") is a download utility designed for the Debian distribution of GNU/Linux that downloads files from several mirrors in order to build an optical disk image. Currently Ubuntu, Fedora, Solaris, and FreeBSD are also available through Jigdo.
A typical application of Jigdo is with its jigdo-file utility. A user that wishes to assemble a disk image downloads a relatively very small file called imagename.jigdo. The jigdo-file utility invoked with this file as an argument then proceeds to fetch additional files from the Internet: imagename.template and a series of .deb files that are listed in the .jigdo file. It then uses the mkisofs utility to build the ISO image.
Jigdo was implemented in Debian in order to reduce the need to have many CD image mirror sites, locations with sufficient disk space and bandwidth to serve numerous 650 MB files (and in more recent times, 4.7 GB files for DVD images). Instead, Jigdo files allow mirrors to carry the regular Debian archive, where packages are not grouped together in image files and instead kept separately where they are also accessible through apt-get and still allow for the making of optical disk images.
Since the release of Fedora 9 Alpha, all future release of Fedora will provide jigdo as an alternative download method for people without bittorrent access. Also, jigdo versions of Fedora 8 discs are available as well as many others variants

Where do i download the jigdo utility? Is it only used by Debain or i can use it for my own Downloads too? Help me. i want to use jigdo as not much people are aware of it so i can get max speed. If i'm not wrong!?? Help Guys!

I'm not sure if you could use it. I gave you the information that i had! I haven't used it for myself. i guess you cannot use it for private download as there won't be any servers or users that could implement it for the P2P type. Not sure though!
