- ;;; 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.
