+<title>Best practices for meta-packages</title>
+<para>
+A meta-package is a mostly empty package that makes it easy to install a
+coherent set of packages that can evolve over time. It achieves this by
+depending on all the packages of the set. Thanks to the power of APT, the
+meta-package maintainer can adjust the dependencies and the user's system
+will automatically get the supplementary packages. The dropped packages
+that were automatically installed will be also be marked as removal
+candidates (and are even automatically removed by <command>aptitude</command>).
+<systemitem role="package">gnome</systemitem> and
+<systemitem role="package">linux-image-amd64</systemitem> are two examples
+of meta-packages (built by the source packages
+<systemitem role="package">meta-gnome2</systemitem> and
+<systemitem role="package">linux-latest</systemitem>).
+</para>
+<para>
+The long description of the meta-package must clearly document its purpose
+so that the user knows what he will lose if he removes the package. Being
+explicit about the consequences is recommended. This is particularly
+important for meta-packages which are installed during initial
+installation and that have not been explicitly installed by the user.
+Those tend to be important to ensure smooth system upgrades and
+the user should be discouraged from uninstalling them to avoid
+potential breakages.
