[TYPO3-mvc] Using extbase in cron scripts / scheduler tasks

[Axel Böswetter]

Hi list,

as the topic says, is there a way to use the extbase framework within cron 
scripts respectivly scheduler tasks? What has to be instantiated to do so? 
In my special case I already have an extbase-based extension. Now I want 
to implement a scheduler task and want to make use of the persistence functionality 
of extbase, which means using the repository objects of my existing extension.
Is this already possible? How?
