Usage: %s [OPTION-OR-FILENAME]...\n\
\n\
Run Emacs, the extensible, customizable, self-documenting real-time\n\
display editor. The recommended way to start Emacs for normal editing\n\
is with no options at all.\n\
\n\
Run M-x info RET m emacs RET m emacs invocation RET inside Emacs to\n\
read the main documentation for these command-line arguments.\n\
\n\
Initialization options:\n\
\n\
--batch do not do interactive display; implies -q\n\
--daemon start a server in the background\n\
--debug-init enable Emacs Lisp debugger for init file\n\
--display, -d DISPLAY use X server DISPLAY\n\
--no-desktop do not load a saved desktop\n\
--no-init-file, -q load neither ~/.emacs nor default.el\n\
--no-shared-memory, -nl do not use shared memory\n\
--no-site-file do not load site-start.el\n\
--no-splash do not display a splash screen on startup\n\
--no-window-system, -nw do not communicate with X, ignoring $DISPLAY\n\
--quick, -Q equivalent to -q --no-site-file --no-splash\n\
--script FILE run FILE as an Emacs Lisp script\n\
--terminal, -t DEVICE use DEVICE for terminal I/O\n\
--user, -u USER load ~USER/.emacs instead of your own\n\
\n%s"
#define USAGE2 "\
Action options:\n\
\n\
FILE visit FILE using find-file\n\
+LINE go to line LINE in next FILE\n\
+LINE:COLUMN go to line LINE, column COLUMN, in next FILE\n\
--directory, -L DIR add DIR to variable load-path\n\
--eval EXPR evaluate Emacs Lisp expression EXPR\n\
--execute EXPR evaluate Emacs Lisp expression EXPR\n\
--file FILE visit FILE using find-file\n\
--find-file FILE visit FILE using find-file\n\
--funcall, -f FUNC call Emacs Lisp function FUNC with no arguments\n\
--insert FILE insert contents of FILE into current buffer\n\

Display options:\n\

--border-color, -bd COLOR main border color\n\
--border-width, -bw WIDTH width of main border\n\
--color, --color=MODE override color mode for character terminals;\n\
MODE defaults to `auto', and can also\n\
be `never', `auto', `always',\n\
or a mode name like `ansi8'\n\
--cursor-color, -cr COLOR color of the Emacs cursor indicating point\n\
--font, -fn FONT default font; must be fixed-width\n\
--foreground-color, -fg COLOR window foreground color\n\
--fullheight, -fh make the first frame high as the screen\n\
--fullscreen, -fs make first frame fullscreen\n\
--fullwidth, -fw make the first frame wide as the screen\n\
--maximized, -mm make the first frame maximized\n\
--geometry, -g GEOMETRY window geometry\n\
--no-bitmap-icon, -nbi do not use picture of gnu for Emacs icon\n\
--iconic start Emacs in iconified state\n\
--internal-border, -ib WIDTH width between text and main border\n\
--line-spacing, -lsp PIXELS additional space to put between lines\n\
--mouse-color, -ms COLOR mouse cursor color in Emacs window\n\
--name NAME title for initial Emacs frame\n\
--no-blinking-cursor, -nbc disable blinking cursor\n\
