A few days ago, I was sponsoring some packages. My laptop has something broken and it sometimes shows irreproducible errors, so I used another computer to make the package builds... I did an error. I didn't do it with pbuilder... so the result was a few ftbfs.
To avoid this to happen again, I've prepared my own autobuilder with a incoming system with a few scripts writen by Matt Brown.
I suppose it will do my sponsors have his/her packages uploaded faster and I don't forget again to built them in a jail!
