Debian Pure Blends tasks for new installations
This package installs a choice of a default installation for each Debian Pure Blend when run from the Debian installer. The installation includes the tasks package of the blend, so a subsequent invocation of tasksel enables the choice of individual tasks. . The package is intended to be installed in the base system. Later (un)installation is harmless, but has no effect.
