-If you have a pbuilder already setup, it's fairly easy to setup an environment with the custom toolchain:
-
-	sudo cp /var/cache/pbuilder/base.tgz \
-		/var/cache/pbuilder/base-reproducible.tgz
-	sudo pbuilder --login --save-after-exec --basetgz \
-		/var/cache/pbuilder/base-reproducible.tgz
-	echo 'deb http://reproducible.alioth.debian.org/debian/ ./' \
-		> /etc/apt/sources.list.d/reproducible.list
-	apt-get update
-	apt-get install dpkg dpkg-dev debhelper dh-python discount

-Once that's done, rebuilding a package can be done through:
-
-	apt-get source --download-only acl
-	sudo DEB_BUILD_OPTIONS=nocheck pbuilder --build --basetgz \
-		/var/cache/pbuilder/base-reproducible.tgz acl_*.dsc
-	mkdir b1 b2

-	dcmd cp /var/cache/pbuilder/result/acl_*.changes b2
-	sudo dcmd rm /var/cache/pbuilder/result/acl_*.changes

-diffp is useful to check the result:
