a small phonological question about the French 'r'.

For those one the list who are very good at phonology, I have a small
question. What is the phonological status of the French 'r'? Can it be
better described as an uvular fricative or an uvular trill? Because at
this PoA I have difficulties to know what I'm really doing when I
pronounce this sound.

        This question is conlang-related as I use this sound in Chasma"o"cho,
and for the purpose of finding the possible consonnant clusters in this
language, I have to know the phonological status of this consonnant. So,
fricative or trill?

        Thanks in advance for your help.
