| 28 | ;; This file parses the command line and gets Emacs running. Options on |
| 29 | ;; the command line are handled in precedence order. The order is the |
| 30 | ;; one in the list below; first described means first handled. Options |
| 31 | ;; within each category (delimited by a bar) are handled in the order |
| 32 | ;; encountered on the command line. |
| 33 | |
| 34 | ;; ------------------------- |
| 35 | ;; -version Print Emacs version to stderr, then exit |
| 36 | ;; --version successfully right away. |
| 37 | ;; This option is handled by emacs.c |
| 38 | ;; ------------------------- |
| 39 | ;; -help Print a short usage description and exit |
| 40 | ;; --help successfully right away. |
| 41 | ;; This option is handled by emacs.c |
| 42 | ;; ------------------------- |
| 43 | ;; -nl Do not use shared memory (for systems that |
| 44 | ;; -no-shared-memory support this) for the dumped Emacs data. |
| 45 | ;; This option is handled by emacs.c |
| 46 | ;; |
| 47 | ;; -map For VMS. |
| 48 | ;; --map-data This option is handled by emacs.c |
| 49 | ;; ------------------------- |
| 50 | ;; -t FILE Use FILE as the name of the terminal. |
| 51 | ;; --terminal FILE Using this implies "-nw" also. |
| 52 | ;; This option is handled by emacs.c |
| 53 | ;; ------------------------- |
| 54 | ;; -d DISPNAME Use DISPNAME as the name of the X |
| 55 | ;; -display DISPNAME display for the initial frame. |
| 56 | ;; --display DISPNAME This option is handled by emacs.c |
| 57 | ;; ------------------------- |
| 58 | ;; -nw Do not use a windows system (but use the |
| 59 | ;; --no-window-system terminal instead.) |
| 60 | ;; This option is handled by emacs.c |

| 68 | ;; --no-init-file "site-start" is still loaded. |
| 69 | ;; ------------------------- |
| 70 | ;; -no-site-file Do not load "site-start.el". (This is the ONLY |
| 71 | ;; --no-site-file way to prevent loading that file.) |

| 74 | ;; --no-splash |

| 83 | ;; -i ICONTYPE Set type of icon using when Emacs is |
| 84 | ;; -itype ICONTYPE iconified under X. |
