jigdo and its files

[Peter Colton <debian.user@bissybox.com>]

	Hello all,

	I been using jigdo for the dvd images of Etch "testing" over the last couple 
of mouths. From :
http://cdimage.debian.org/cdimage/weekly-builds/i386/jigdo-dvd/
The jigdo files I downloaded where in the format of :
debian-testing-i386-DVD-1.jigdo
debian-testing-i386-DVD-1.template       :  and so on

But now there is more jigdo files in the format of :
debian-testing-i386-DVD-binary-1.jigdo
debian-testing-i386-DVD-binary-1.template

So the question is whats the difference ? and which format of jigdo file do I 
use ?
