r.f.e. emacs tutorial

[Jude DaShiell]

In some future version of emacs would it be possible to include a session
on the emacs debugger for when .emacs and similar files get messed up how
to use emacs --debug to locate problems and repair those problems?

There seems to be no such option as --debug according
to the man page emacs(1) (GNU Emacs 26.1,
2007 April 13 - hm ... that old a man page?)

OTOH, Emacs doesn't report an error on
$ emacs --debug # maybe because it is a prefix of
--debug-init, as e.g. --xyz does report
'Unknown option'.

(If indeed a prefix thing, it should be dropped IMO.
Error prone and doesn't look right - by
definition, even.)

Anyway, keeping up with the man page, it says:

  --debug-init
    Enable Emacs Lisp debugger during the  process‐
    ing  of  the  user init file ~/.emacs.  This is
    useful for debugging problems in the init file.

Here,

  (info "(emacs) Initial Options")

it says

  --debug-init’
      Enable the Emacs Lisp debugger for errors in the init file.  *Note
      Entering the Debugger on an Error: (elisp)Error Debugging.

which is a reference to

  (info "(elisp) Error Debugging")

where

  (how-many "init") ; 4

HIH :)
