+       tristate "CCITT X.25 Packet Layer"
+       ---help---
+         X.25 is a set of standardized network protocols, similar in scope to
+         frame relay; the one physical line from your box to the X.25 network
+         entry point can carry several logical point-to-point connections
+         (called "virtual circuits") to other computers connected to the X.25
+         network. Governments, banks, and other organizations tend to use it
+         to connect to each other or to form Wide Area Networks (WANs). Many
+         countries have public X.25 networks. X.25 consists of two
+         protocols: the higher level Packet Layer Protocol (PLP) (say Y here
+         if you want that) and the lower level data link layer protocol LAPB
+         (say Y to "LAPB Data Link Driver" below if you want that).
+
+         You can read more about X.25 at <http://www.sangoma.com/tutorials/x25/> and
+         <http://docwiki.cisco.com/wiki/X.25>.
+         Information about X.25 for Linux is contained in the files
+         <file:Documentation/networking/x25.txt> and
+         <file:Documentation/networking/x25-iface.txt>.
+
+         One connects to an X.25 network either with a dedicated network card
+         using the X.21 protocol (not yet supported by Linux) or one can do
+         X.25 over a standard telephone line using an ordinary modem (say Y
+         to "X.25 async driver" below) or over Ethernet using an ordinary
+         Ethernet card and the LAPB over Ethernet (say Y to "LAPB Data Link
+         Driver" and "LAPB over Ethernet driver" below).
+
+         To compile this driver as a module, choose M here: the module
+         will be called x25. If unsure, say N.
