Dear Uli,

Please note that in the case of the Portuguese grammar,
interfacing the deep grammar with our pre-processing
tools (POS tagger, lemmatizer, morphological analyzer,
NER) are done exclusively via PIC, so having PET
without PIC would knock out our grammar from running
on it.

All the best,


P.S.: Francisco has already sent to Bernd a detailed description
of the problem with PET we reported in Paris, together with
our grammar so that you will be able to reproduce it on your side.
For the sake of the recording he'll be submiting a ticket
in PET bug tracker as well.
