Ease distribution of large files over the Internet
Description
Jigsaw Download (for short jigdo) is a scheme developed primarily to make it
easy to distribute huge filesystem images (e.g. CD (ISO9660) or DVD (UDF)
images) over the internet, but it could also be used for other data which is
awkward to handle due to its size, like audio/video files or large software
packages.
jigdo tries to ensure that the large file is downloaded in small parts which can
be stored on different servers. People who want to download the image do so by
telling the jigdo download tool to process one ".jigdo" file; using it, jigdo
downloads the parts and reassembles the image. jigdo-file is used to prepare the
files for download.
