# File lib/byebug/commands/where.rb, line 19 def self.description <<-DESCRIPTION w[here]|bt|backtrace #{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. DESCRIPTION end
