jigdo and debian-cd

[Lucio Crusca <ifts@pixel.it>]

Hello everybody.

I work for a company which is a Debian CDs vendor. We have being selling only 
Woody official CDs for a while, but recenlty a number of customers asked us 
the Sarge CDs and I'm the one responsible for maintaining updated ISO images.

First of all I installed jigdo-lite and built the 13 ISO images. Then I found 
a file, namely README.CD-manufacture, on one of the mirrors. This file tells 
to use the debian-cd package which seems to have nothing to do with jigdo.

All I need is to have working official Sarge ISO images up to date. The 
questions:
1 - What should I use, debian-cd or jigdo? 
1.1 - Just in case the answer is "jigdo", is there a way to make the process 
of updating images less interactive (not interactive at all) so that 
jigdo-lite can be put in a shell script?
1.1.1 - Does this shell script already exist somewhere?
2 - How do I include non-us software in my Sarge images?


Thanks in advance,
L.
