43 "Buffer to show after starting Emacs.
44 If the value is nil and `inhibit-startup-screen' is nil, show the
45 startup screen. If the value is a string, switch to a buffer
46 visiting the file or directory that the string specifies. If the
47 value is a function, call it with no arguments and switch to the buffer
48 that it returns. If t, open the `*scratch*' buffer.
50 When `initial-buffer-choice' is non-nil, the startup screen is
51 inhibited.
53 If you use `emacsclient' with no target file, then it obeys any
54 string or function value that this variable has."
59 ;; Note sure about hard-coding this as an option...
67 "Non-nil inhibits the startup screen.
69 This is for use in your personal init file (but NOT site-start.el),
70 once you are familiar with the contents of the startup screen."
79 ;; The mechanism used to ensure that only end users can disable this
80 ;; message is not complex. Clearly, it is possible for a determined
81 ;; system administrator to inhibit this message anyway, but at least
82 ;; they will do so with knowledge of why the Emacs developers think
83 ;; this is a bad idea.
85 "Non-nil inhibits the initial startup echo area message.
87 The startup message is in the echo area as it provides information
88 about GNU Emacs and the GNU system in general, which we want all
89 users to see. As this is the least intrusive startup message,
90 this variable gets specialized treatment to prevent the message
91 from being disabled site-wide by systems administrators, while
92 still allowing individual users to do so.
94 Setting this variable takes effect only if you do it with the
95 customization buffer or if your init file contains a line of this
96 form:
98 If your init file is byte-compiled, use the following form
99 instead:
101 Thus, someone else using a copy of your init file will see the
102 startup message unless he personally acts to inhibit it."

323 This is very similar to `emacs-startup-hook'. The only difference

353 This file is loaded at run-time before `~/.emacs'. It contains inits
354 that need to be in place for the entire site, but which, due to their
355 higher incidence of change, don't make sense to load into Emacs's
356 dumped image. Thus, the run-time load order is: 1. file described in

359 Don't use the `site-start.el' file for things some users may not like.

361 override them. Users can prevent loading `default.el' with the `-q'
362 option or by setting `inhibit-default-init' in their own init files,
363 but inhibiting `site-start.el' requires `--no-site-file', which
364 is less convenient.

367 it visible in the relevant context. However, actually customizing it
