NSBezierPath description...

...shows the path segments as Postscript commands. So the following code:

  id p= [NSBezierPath bezierPathWithRect: NSMakeRect(10,20,200,100)];
  NSLog(@"p: %@",[p description]);

yields this output:

  Bounds: {{10, 20}, {200, 100}}
  Control point bounds: {{10, 20}, {200, 100}}
    10.000000 20.000000 moveto
    210.000000 20.000000 lineto
    210.000000 120.000000 lineto
    10.000000 120.000000 lineto
    closepath
    10.000000 20.000000 moveto

Neat!
