animation "frame_rate"

Can anybody tell me how to get the frame-rate and start/end times of an animation? Think I usually see the start/end at the bottom of visual-scene-node info, but the frame_rate info isn’t always in that spot.

I normally just get the start/stop times by finding the min/max values in all of the animation-channels’ input-times. Maybe this is a bad idea?

Thanks,
Matt
