"Mode for debugging Emacs Lisp using a backtrace.

A line starts with `*' if exiting that frame will call the debugger.
Type \\[debugger-frame] or \\[debugger-frame-clear] to set or remove the `*'.
A frame marked with `*' in the backtrace means that exiting that
frame will enter the debugger. You can flag frames to enter the
debugger when frame is exited with \\[debugger-frame], and remove
the flag with \\[debugger-frame-clear].
When in debugger due to frame being exited,
use the \\[debugger-return-value] command to override the value
being returned from that frame.
When in debugger invoked due to exiting a frame which was flagged
with a `*', you can use the \\[debugger-return-value] command to
override the value being returned from that frame when the debugger
exits.
Use \\[debug-on-entry] and \\[cancel-debug-on-entry] to control
which functions will enter the debugger when called.
