build

Hi Nicolas,

thank you for your answer.
Filtering some files because of some rules (e.g. derived state) would  
be very cool.
Should I log an enhancement request?

Btw: I locally changed the WTP sources to not consider derived  
ressources using the PDE.
How can I create a patched plugin/feature patch to make these changes  
persistent and to share them with my colleagues?

Best regards,
Patric
