;;; Quick hack to use emacs as mail editor. There are a *bunch* of
|
|
;;; changes scattered throughout emacs to make this work, namely:
|
|
;;; (1) mod to sysdep.c to allow emacs to attach to a process other
|
|
;;; than the one that originally spawned it.
|
|
;;; (2) mod to kepteditor.com to define the logical emacs_parent_pid
|
|
;;; which is what sysdep.c looks for, and define the logical
|
|
;;; emacs_command_args which contains the command line
|
|
;;; (3) mod to re-parse command line arguments from emacs_command_args
|
|
;;; then execute them as though emacs were just starting up.
