• 1.69 is only avaiable in English at the moment and we should try to accomplish this with our mojosetup_dummy installer
• how can we copy the same behavior which is possible with loki_setup and the component tag

• try to map the component tag support from loki_setup to mojosetup (ask on the mailinglist etc.)
• start with the English installers
