+        Usage: pry-backtrace [OPTIONS] [--help]
+
+        Show the backtrace for the position in the code where Pry was started. This can
+        be used to infer the behavior of the program immediately before it entered Pry,
+        just like the backtrace property of an exception.
+
+        NOTE: if you are looking for the backtrace of the most recent exception raised,
+        just type: `_ex_.backtrace` instead.
+        See: https://github.com/pry/pry/wiki/Special-Locals
