mouth confusion

[coder0xff]

Yet another *sigh*:

Would someone please provide the information for mouth?

http://developer.valvesoftware.com/wiki ... C%29#mouth

What's with the number zero as the first parameter in the example?

Are the floats x, y, z values? pitch yaw roll? something different?

Edit*********
Can you have more than one mouth for a $model?

While were at it - instead of making more threads as I get them:

defaultflex, frame, and spherenormals have next to no documentation either.

I guess if no one ever uses the options then I need not implement them in DuctTape. Otherwise, I need a guru to clear these up for me.
