29:  How do I debug a .emacs file?
  
  First start Emacs with the `-q' command line option.  Then, in the
  *scratch* buffer, type the following:
  
    (setq debug-on-error t) LFD
    (load-file "~/.emacs") LFD
  
  (Type LFD by pressing C-j.)
  
  If you have an error in your .emacs file, this will invoke the debugger
  when the error occurs.  If you don't know how to use the debugger do
  (setq stack-trace-on-error t) instead.
  
  WARNING: this will not discover errors caused by trying to do something
  that requires the terminal/window-system initialization code to have
  been loaded.  See question 129.
