+Start emacs with minimum customizations. This is similar to using @samp{-q},
@samp{--no-site-file}, @samp{--no-site-lisp}, and @samp{--no-splash}
together. This also stops Emacs from processing X resources by
setting @code{inhibit-x-resources} to @code{t} (@pxref{Resources}).
@item CDPATH
Used by the @code{cd} command to search for the directory you specify,
when you specify a relative directory name.
+@item DBUS_SESSION_BUS_ADDRESS
+Used by D-Bus when Emacs is compiled with it. Usually, there is no
+need to change it. Setting it to a dummy address, like
+@samp{unix:path=/tmp/foo}, suppresses connections to the D-Bus session
+bus.
@item EMACSDATA
Directory for the architecture-independent files that come with Emacs.

@code{temporary-file-directory}, which specifies a directory in which

@item TZ
This specifies the current time zone and possibly also daylight

When passing a font name to Emacs on the command line, you may need to
``quote'' it, by enclosing it in quotation marks, if it contains

Depending on your terminal's capabilities, Emacs might be able to turn
on a color mode for 8, 16, 88, or 256 as the value of @var{num}. If
there is no mode that supports @var{num} colors, Emacs acts as if
-@var{num} were 0, i.e.@: it uses the terminal's default color support

If @var{mode} is omitted, it defaults to @var{ansi8}.
By default, Emacs uses an icon containing the Emacs logo. On
desktop environments such as Gnome, this icon is also displayed in
-other contexts, e.g.@: when switching into an Emacs frame. The

@samp{-nbi} or @samp{--no-bitmap-icon} option tells Emacs to let the

rectangle containing the frame's title.
