-config PPP
-	tristate "PPP (point-to-point protocol) support"
-	select SLHC
-	---help---
-	  PPP (Point to Point Protocol) is a newer and better SLIP.  It serves
-	  the same purpose: sending Internet traffic over telephone (and other
-	  serial) lines.  Ask your access provider if they support it, because
-	  otherwise you can't use it; most Internet access providers these
-	  days support PPP rather than SLIP.
-
-	  To use PPP, you need an additional program called pppd as described
-	  in the PPP-HOWTO, available at
-	  <http://www.tldp.org/docs.html#howto>.  Make sure that you have
-	  the version of pppd recommended in <file:Documentation/Changes>.
-	  The PPP option enlarges your kernel by about 16 KB.
-
-	  There are actually two versions of PPP: the traditional PPP for
-	  asynchronous lines, such as regular analog phone lines, and
-	  synchronous PPP which can be used over digital ISDN lines for
-	  example.  If you want to use PPP over phone lines or other
-	  asynchronous serial lines, you need to say Y (or M) here and also to
-	  the next option, "PPP support for async serial ports".  For PPP over
-	  synchronous lines, you should say Y (or M) here and to "Support
-	  synchronous PPP", below.
-
-	  If you said Y to "Version information on all symbols" above, then
-	  you cannot compile the PPP driver into the kernel; you can then only
-	  compile it as a module. To compile this driver as a module, choose M
-	  here. The module will be called ppp_generic.
-
-config PPP_MULTILINK
-	bool "PPP multilink support (EXPERIMENTAL)"
-	depends on PPP && EXPERIMENTAL
-	help
-	  PPP multilink is a protocol (defined in RFC 1990) which allows you
-	  to combine several (logical or physical) lines into one logical PPP
-	  connection, so that you can utilize your full bandwidth.
-
-	  This has to be supported at the other end as well and you need a
-	  version of the pppd daemon which understands the multilink protocol.
-
-	  If unsure, say N.
-
-config PPP_FILTER
-	bool "PPP filtering"
-	depends on PPP
-	help
-	  Say Y here if you want to be able to filter the packets passing over
-	  PPP interfaces.  This allows you to control which packets count as
-	  activity (i.e. which packets will reset the idle timer or bring up
-	  a demand-dialed link) and which packets are to be dropped entirely.
-	  You need to say Y here if you wish to use the pass-filter and
-	  active-filter options to pppd.
-
-	  If unsure, say N.
-
-config PPP_ASYNC
-	tristate "PPP support for async serial ports"
-	depends on PPP
-	select CRC_CCITT
-	---help---
-	  Say Y (or M) here if you want to be able to use PPP over standard
-	  asynchronous serial ports, such as COM1 or COM2 on a PC.  If you use
-	  a modem (not a synchronous or ISDN modem) to contact your ISP, you
-	  need this option.
-
-	  To compile this driver as a module, choose M here.
-
-	  If unsure, say Y.
-
-config PPP_SYNC_TTY
-	tristate "PPP support for sync tty ports"
-	depends on PPP
-	help
-	  Say Y (or M) here if you want to be able to use PPP over synchronous
-	  (HDLC) tty devices, such as the SyncLink adapter. These devices
-	  are often used for high-speed leased lines like T1/E1.
-
-	  To compile this driver as a module, choose M here.
-
-config PPP_DEFLATE
-	tristate "PPP Deflate compression"
-	depends on PPP
-	select ZLIB_INFLATE
-	select ZLIB_DEFLATE
-	---help---
-	  Support for the Deflate compression method for PPP, which uses the
-	  Deflate algorithm (the same algorithm that gzip uses) to compress
-	  each PPP packet before it is sent over the wire.  The machine at the
-	  other end of the PPP link (usually your ISP) has to support the
-	  Deflate compression method as well for this to be useful.  Even if
-	  they don't support it, it is safe to say Y here.
-
-	  To compile this driver as a module, choose M here.
-
-config PPP_BSDCOMP
-	tristate "PPP BSD-Compress compression"
-	depends on PPP
-	---help---
-	  Support for the BSD-Compress compression method for PPP, which uses
-	  the LZW compression method to compress each PPP packet before it is
-	  sent over the wire. The machine at the other end of the PPP link
-	  (usually your ISP) has to support the BSD-Compress compression
-	  method as well for this to be useful. Even if they don't support it,
-	  it is safe to say Y here.
-
-	  The PPP Deflate compression method ("PPP Deflate compression",
-	  above) is preferable to BSD-Compress, because it compresses better
-	  and is patent-free.
-
-	  Note that the BSD compression code will always be compiled as a
-	  module; it is called bsd_comp and will show up in the directory
-	  modules once you have said "make modules". If unsure, say N.
