;;; Commentary:
-;; This file parses the command line and gets Emacs running. Options on
-;; the command line are handled in precedence order. The order is the
-;; one in the list below; first described means first handled. Options
-;; within each category (delimited by a bar) are handled in the order
-;; encountered on the command line.
-
-;; -------------------------
-;; -version Print Emacs version to stderr, then exit
-;; --version successfully right away.
-;; This option is handled by emacs.c
-;; -------------------------
-;; -help Print a short usage description and exit
-;; --help successfully right away.
-;; This option is handled by emacs.c
-;; -------------------------
-;; -nl Do not use shared memory (for systems that
-;; -no-shared-memory support this) for the dumped Emacs data.
-;; This option is handled by emacs.c
-;;
-;; -map For VMS.
-;; --map-data This option is handled by emacs.c
-;; -------------------------
-;; -t FILE Use FILE as the name of the terminal.
-;; --terminal FILE Using this implies "-nw" also.
-;; This option is handled by emacs.c
-;; -------------------------
-;; -d DISPNAME Use DISPNAME as the name of the X
-;; -display DISPNAME display for the initial frame.
-;; --display DISPNAME This option is handled by emacs.c
-;; -------------------------
-;; -nw Do not use a windows system (but use the
-;; --no-windows terminal instead.)
-;; This option is handled by emacs.c
-;; -------------------------
-;; -batch Execute noninteractively (messages go to stdout,
-;; --batch variable noninteractive set to t)
-;; This option is handled by emacs.c
-;; -------------------------
-;; -q Do not load user's init file and do not load
-;; -no-init-file "default.el". Regardless of this switch,
-;; --no-init-file "site-start" is still loaded.
-;; -------------------------
-;; -no-site-file Do not load "site-start.el". (This is the ONLY
-;; --no-site-file way to prevent loading that file.)
-;; -------------------------
-;; -u USER Load USER's init file instead of the init
-;; -user USER file belonging to the user starting Emacs.
-;; --user USER
-;; -------------------------
-;; -debug-init Don't catch errors in init files; let the
-;; --debug-init debugger run.
-;; -------------------------
-;; -i ICONTYPE Set type of icon using when Emacs is
-;; -itype ICONTYPE iconified under X.
-;; --icon-type ICONTYPE This option is passed on to term/x-win.el
-;;
-;; -iconic Start Emacs iconified.
-;; --iconic This option is passed on to term/x-win.el
-;; -------------------------
-;; Various X options for colors/fonts/geometry/title etc.
-;; These options are passed on to term/x-win.el which see. Certain
-;; of these are also found in term/pc-win.el
-;; -------------------------
-;; FILE Visit FILE.
-;; -visit FILE
-;; --visit FILE
-;; -file FILE
-;; --file FILE
-;;
-;; -L DIRNAME Add DIRNAME to load-path
-;; -directory DIRNAME
-;; --directory DIRNAME
-;;
-;; -l FILE Load and execute the Emacs lisp code
-;; -load FILE in FILE.
-;; --load FILE
-;;
-;; -f FUNC Execute Emacs lisp function FUNC with
-;; -funcall FUNC no arguments. The "-e" form is outdated
-;; --funcall FUNC and should not be used. (It's a typo
-;; -e FUNC promoted to a feature.)
-;;
-;; -eval FORM Execute Emacs lisp form FORM.
-;; --eval FORM
-;; -execute EXPR
-;; --execute EXPR
-;;
-;; -insert FILE Insert the contents of FILE into buffer.
-;; --insert FILE
-;; -------------------------
-;; -kill Kill (exit) Emacs right away.
