Пакет jigdo: Информация

Jigsaw Download, or short jigdo, is an intelligent tool that can be used on the
pieces of any chopped-up big file to create a special "template" file which
makes reassembly of the file very easy for users who only have the pieces.

What makes jigdo special is that there are no restrictions on what
offsets/sizes the individual pieces have in the original big image. This makes
the program very well suited for distributing CD/DVD images (or large zip/tar
archives) because you can put the files of the CD on an FTP server - when jigdo
is presented the files along with the template you generated, it is able to
recreate the CD image.
