+:1. Preparing the cowbuilder:
+============================
+
+ sudo aptitude install cowdancer grep-dctrl wget
+ sudo cowbuilder --create --distribution lenny --basepath /var/cache/pbuilder/testing-base.cow
+
+2. Getting the list of packages to build:
+=========================================
+
+ getlist lenny
+
+Will fetch the Sources.gz for main and contrib of the distribution you
+choose and creates two files:
+
+ 1. list.lenny
+ 2. list.lenny.i368
+
+The first list contains the name of all packages followed by all
+architectures it can be build on. The second list Contains the names of
+all packages which can be build on your arch.
+
+3. Setting the rebuild variables:
+=================================
+
+The only setting should change is the BASEPATH variable. It must match
+the --basepath option you gave.
+
+The other settings BUILDDIR and LOGDIR are optional.
+
+4. Rebuilding the archive
+=========================
+
+ rebuild list.lenny.i386 lenny
+
+Will attempt to build all packages appearing in list.testing.i368. It will
+temporarily build them in $BUILDDIR/$PACKAGE and will use $LOGDIR to create
+lock- and logfiles.
+
+NOTES:
+======
+
+ - On a machine with more than one processor you can run multiple instances
+ of the rebuild script in order to speed up the build process by building
+ multiple packages concurrently
+
+ - When building for a different distribution (testing) than the one the host
+ system is running (sid) you got to make sure that apt-get source fetches the
+ right sources. Otherwise you'll rebuild the packages from sid in a testing
+ environment and get false-positive FTBFS.
