\footnotesize\begin{verbatim}Britney, the debian testing updater script

This is the script that updates the testing_ distribution. It is executed
each day after the installation of the updated packages. It generates the 
`Packages' files for the testing distribution, but it does so in an
intelligent manner; it try to avoid any inconsistency and to use only
non-buggy packages.

For more documentation on this script, please read the Developers Reference.

This method checks if the `pkg` package from the `arch` architecture
can be installed (excluding `broken` packages) within the system
`system` along with all its dependencies. This means that all the
conflicts relationships are checked in order to achieve the test
co-installability of the package.

in memory. The available fields are Version, Source, Pre-Depends,
Depends, Conflicts, Provides and Architecture.

After reading the packages, reverse dependencies are computed
and saved in the `rdepends' keys, and the `Provides' field is
used to populate the virtual packages list.

The dependencies are parsed with the apt.pkg.ParseDepends method,
and they are stored both as the format of its return value and
text.

The method returns a tuple. The first element is a list where
every item represents a binary package as a dictionary; the second
element is a dictionary which maps virtual packages to real
packages that provide it.

The upload urgencies are read from the `Urgency' file within the
directory specified as `basedir' parameter. The file contains rows
with the format:

The method returns a dictionary where the key is the binary package
name and the value is the greatest urgency from the versions of the
package that are higher then the testing one.
