238 --chdir DIR change to directory DIR\n\
239 --daemon start a server in the background\n\
240 --debug-init enable Emacs Lisp debugger for init file\n\
241 --display, -d DISPLAY use X server DISPLAY\n\
244 --no-desktop do not load a saved desktop\n\
245 --no-init-file, -q load neither ~/.emacs nor default.el\n\

263 FILE visit FILE using find-file\n\
264 +LINE go to line LINE in next FILE\n\
265 +LINE:COLUMN go to line LINE, column COLUMN, in next FILE\n\
266 --directory, -L DIR prepend DIR to load-path (with :DIR, append DIR)\n\
267 --eval EXPR evaluate Emacs Lisp expression EXPR\n\
268 --execute EXPR evaluate Emacs Lisp expression EXPR\n\
271 --file FILE visit FILE using find-file\n\
272 --find-file FILE visit FILE using find-file\n\
273 --funcall, -f FUNC call Emacs Lisp function FUNC with no arguments\n\

290 --color, --color=MODE override color mode for character terminals;\n\
291 MODE defaults to `auto', and\n\
292 can also be `never', `always',\n\
293 or a mode name like `ansi8'\n\
294 --cursor-color, -cr COLOR color of the Emacs cursor indicating point\n\
295 --font, -fn FONT default font; must be fixed-width\n\

320 --help display this help and exit\n\
321 --version output version information and exit\n\
325 You can generally also specify long option names with a single -; for\n\
326 example, -batch as well as --batch. You can use any unambiguous\n\
327 abbreviation for a --option.\n\
329 Various environment variables and window system resources also affect\n\
330 the operation of Emacs. See the main documentation.\n\
