[pstricks] Tracing angles between two lines defined by nodes

Hi all,

if I have three nodes, say C, P1 and P2,
I can think of two lines, departing from C,  "line 1" connecting C to P1,
the other "line 2" connecting C to P2.
My question is this:
How can I draw an arc, centered in C, going from line 1 to line 2
indicating the angle between them ?
