Howto build Trisquel?

Hello,

well, I would like to build Trisquel. I've downloaded Sources DVD and I thought, that I'll find there some tips for building Trisquel, but I didn't. At your web page I've found that:

Trisquel is built using debootstrap, using a script that also installs a metapackage and its dependencies (to build each edition of the distro), compresses it into a squashfs image and builds the .iso using isolinux. The script also applies some changes to the debootstrap directory, to allow it to run in a live environment.
The makedistro script also builds a set of source code DVDs.

I have a two questions:
1. How can I build Trisquel using debootstrap? Is there any tutorial at your webpage about it?
2. You're writing, that there is a makedistro script which build set of source code DVDs. I can't download this - link is broken. Can you fix it?

Thanks.
