@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.
This is used to initialize the variable @code{data-directory}.
This specifies the current time zone and possibly also daylight
saving time information. On MS-DOS, if @env{TZ} is not set in the
environment when Emacs starts, Emacs defines a default value as
-appropriate for the country code returned by DOS. On MS-Windows, Emacs

does not use @env{TZ} at all.
@item USER
The user's login name. See also @env{LOGNAME}. On MS-DOS, this
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

@end table
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
window manager choose what sort of icon to use---usually just a small
rectangle containing the frame's title.
