| 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. |
