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