#{short_description}
Print the entire stack frame. Each frame is numbered; the most recent
frame is 0. A frame number can be referred to in the "frame" command.
"up" and "down" add or subtract respectively to frame numbers shown.
The position of the current frame is marked with -->. C-frames hang
from their most immediate Ruby frame to indicate that they are not
navigable.
