+ tristate "Unix domain sockets"
+ ---help---
+ If you say Y here, you will include support for Unix domain sockets;
+ sockets are the standard Unix mechanism for establishing and
+ accessing network connections. Many commonly used programs such as
+ the X Window system and syslog use these sockets even if your
+ machine is not connected to any network. Unless you are working on
+ an embedded system or something similar, you therefore definitely
+ want to say Y here.
+
+ To compile this driver as a module, choose M here: the module will be
+ called unix. Note that several important services won't work
+ correctly if you say M here and then neglect to load the module.
+
+ Say Y unless you know what you are doing.
