Jigdo

Jigdo（"Jigsaw download"，曲线下载）是为Debian套件设计的下载工具，可以从几个镜像站点下载不同的文件，然后再生成一个iso文件。

A typical application of Jigdo is with its jigdo-file utility. A user that wishes to assemble a CD 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're also apt-gettable, and still allow for the making of CD/DVD images.
