This section is intended to give translators a general idea of each level contents.
level 1: all core Debian Installer packages;
This level is split in five "sublevels" by order of strings priority (sublevel 1 groups together the strings used in all default installs while sublevel 5 groups together very rare strings used only for uncommon architectures; sublevel 2 - 4 are placed somewhere in between).
level 2: all non-core Debian Installer material involved for user interaction screens during a default priority installation of a Debian base system with default choices;
level 3: all material indirectly related to installation;
