It is documented to take an argument, namely
the file name of an ".fc2" file.

But I can't find a file with type ".fc2" anywhere???

I find a lot of ".fcz" files, which seems like what
the Scene.LoadLibraryFace() method should take,
but when I:

poser.Scene.LoadLibraryFace("RuntimelibrariesFaceP4
PhonemesAre.fcz")

Results in: SyntaxError: invalid syntax

I'm doing this to a P4 woman's head, that in the GUI,
allows setting the P4 Phoneme -- "Are" .

When I search the CuriousLabs website there are no hits for "fcz"
and only a few for "fc2" in license agreements where file types
are mentioned, but again, the actual file type seems to be fcz, no fc2.

How can I load these facial expressions using Python?

I'm trying to script the render and save of the full set
of phoneme expressions (for any particular pose), which should be
very easy, except this method (and documentation) seems
to have problems.

(..or is there something fundamentally wrong with my Python syntax?)
