Retrieve a GIF's palette entries using Python Imaging Library (PIL)

[Stuart]

I am using the Python Imaging Library (PIL) to process GIF images. I 
need to be able to retrieve the RGB values for each color palette entry.

I see that the 'Image' class has a 'palette' attribute which returns an 
object of type 'ImagePalette'.  However, the documentation is a bit 
lacking regarding how to maniuplate the ImagePalette class to retrieve 
the palette entries' RGB values.  Can anyone point me to a short example?

Thanks!
