-asynchronous and synchronous subprocesses, unexec (@code{dump-emacs}),
-and networking (@code{open-network-stream}).  Support for various

+application and yank it into a Emacs buffer.  This feature can be
+disabled by setting @code{x-select-enable-clipboard} to @code{nil}.
+One can still do copy and paste with another application from the Edit
+menu.
+
+  On Mac, the role of the coding system for selection that is set by
+@code{set-selection-coding-system} (@pxref{Specify Coding}) is
+two-fold.  First, it is used as a preferred coding system for the
+traditional text flavor that does not specify any particular encodings
+and is mainly used by applications on Mac OS Classic.  Second, it
+specifies the intermediate encoding for the UTF-16 text flavor that is
+mainly used by applications on Mac OS X.
+
+  When pasting UTF-16 text data from the clipboard, it is first
+converted to the encoding specified by the selection coding system
+using the converter in the Mac OS system, and then decoded into the
+Emacs internal encoding using the converter in Emacs.  If the first
+conversion failed, then the UTF-16 data is directly converted to Emacs
+internal encoding using the converter in Emacs.  Copying UTF-16 text
+to the clipboard goes through the inverse path.  The reason for this
+two-path decoding is to avoid subtle differences in Unicode mappings
+between the Mac OS system and Emacs such as various kinds of hyphens,
+and to minimize users' customization.  For example, users that mainly
+use Latin characters would prefer Greek characters to be decoded into
+the @code{mule-unicode-0100-24ff} charset, but Japanese users would
+prefer them to be decoded into the @code{japanese-jisx0208} charset.
+Since the coding system for selection is automatically set according
+to the system locale setting, users usually don't have to set it
+manually.
+
+  The default language environment (@pxref{Language Environments}) is
+set according to the locale setting at the startup time.  On Mac OS,
+the locale setting is consulted in the following order:
+
+@enumerate
+@item
+Environment variables @env{LC_ALL}, @env{LC_CTYPE} and @env{LANG} as
+in other systems.
+
+@item
+Preference @code{AppleLocale} that is set by default on Mac OS X 10.3
+and later.
+
+@item
+Preference @code{AppleLanguages} that is set by default on Mac OS X
+10.1 and later.
+
+@item
+Variable @code{mac-system-locale} that is derived from the system
+language and region codes.  This variable is available on all
+supported Mac OS versions including Mac OS Classic.
+@end enumerate
+
+  The default values of almost all variables about coding systems are
+also set according to the language environment.  So usually you don't
