How do I change the rate of speed on a path?

I would like to increase the rate of speed of a bone along a drawn path.

How can I do this? How is the banking, or slope, of the path changed so that the bone will tilt as it nears the end of the path?

Thanks, Bob

I wrote a video tutorial on paths and dupliframing which explains all this and more. If you have a reasonable internet connection I suggest downloading it:

You change the speed by either editing the ipo curve or deleting the ipo speed curve and changing the pathlen whose value is in frames (the speed ipo take precedence over the pathlen value). To change the banking go into edit mode with the path selected. Select a vert/control point and press the t key (tilt). Then moving the mouse up and down tilts/banks the path.
