[Typo3] How to access a module method via Typoscript

[Jochen Rieger]

Hello,

I'm writing a backend module which lets you administrate RSS-Feeds from 
which an import should be started and their items to be put into the 
tt_news table in order to be in the normal news workflow.

My problem now is how to get the import triggered automatically.

My idea is to put some typoscript code into the root template. E.g. a 
USER object which calls a method within my module class via .userfunc.

Do I have to include the class then via includeLibs or is there any 
other (better) possibility to achieve a triggering via page call?

Cheers,
Jochen
