32 ;; -------------------------
33 ;; -version Print Emacs version to stderr, then exit
34 ;; --version successfully right away.
35 ;; This option is handled by emacs.c
36 ;; -------------------------
37 ;; -help Print a short usage description and exit
38 ;; --help successfully right away.
39 ;; This option is handled by emacs.c
40 ;; -------------------------
41 ;; -nl Do not use shared memory (for systems that
42 ;; -no-shared-memory support this) for the dumped Emacs data.
43 ;; This option is handled by emacs.c
46 ;; --map-data This option is handled by emacs.c
47 ;; -------------------------
48 ;; -t FILE Use FILE as the name of the terminal.
49 ;; --terminal FILE Using this implies "-nw" also.
50 ;; This option is handled by emacs.c
51 ;; -------------------------
52 ;; -d DISPNAME Use DISPNAME as the name of the X-windows
53 ;; -display DISPNAME display for the initial frame.
54 ;; --display DISPNAME This option is handled by emacs.c
55 ;; -------------------------
56 ;; -nw Do not use a windows system (but use the
57 ;; --no-windows terminal instead.)
58 ;; This option is handled by emacs.c
59 ;; -------------------------
60 ;; -batch Execute noninteractively (messages go to stdout,
61 ;; --batch variable noninteractive set to t)
62 ;; This option is handled by emacs.c
63 ;; -------------------------
64 ;; -q Do not load user's init file and do not load
65 ;; -no-init-file "default.el". Regardless of this switch,
66 ;; --no-init-file "site-init.el" is still loaded.
67 ;; -------------------------
68 ;; -no-site-file Do not load "site-init.el". (This is the ONLY
69 ;; --no-site-file way to prevent loading that file.)
70 ;; -------------------------
71 ;; -u USER Load USER's init file instead of the init
72 ;; -user USER file belonging to the user starting Emacs.
74 ;; -------------------------
75 ;; -debug-init Don't catch errors in init files; let the
76 ;; --debug-init debugger run.
77 ;; -------------------------
78 ;; -i ICONTYPE Set type of icon using when Emacs is
79 ;; -itype ICONTYPE iconified under X-windows.
80 ;; --icon-type ICONTYPE This option is passed on to term/x-win.el
82 ;; -iconic Start Emacs iconified under X-windows.
83 ;; --iconic This option is passed on to term/x-win.el
84 ;; -------------------------
85 ;; Various X-windows options for colors/fonts/geometry/title etc.
86 ;; These options are passed on to term/x-win.el which see. Certain
87 ;; of these are also found in term/pc-win.el
88 ;; -------------------------
91 ;; -L DIRNAME Add DIRNAME to load-path
93 ;; --directory DIRNAME
95 ;; -l FILE Load and execute the Emacs lisp code
96 ;; -load FILE in FILE.
99 ;; -f FUNC Execute Emacs lisp function FUNC with
100 ;; -funcall FUNC no arguments. The "-e" form is outdated
101 ;; --funcall FUNC and should not be used. (It's a typo
102 ;; -e FUNC promoted to a feature.)
104 ;; -insert FILE Insert the contents of FILE into buffer.
106 ;; -------------------------
