+;;; 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.
