-configure: Allow overriding uname results
-
-In a cross compile setting it makes no sense to rely on the "uname" values
-reported by the build host system. This patch allows overriding the
-"uname -r", "uname -s" and "uname -m" results with the "UNAME_R", "UNAME_S"
-and "UNAME_M" environment variables.

-pppd: Allow specifying ip-up and ip-down scripts
-
-This patch implements the "ip-up-script" and "ip-down-script" options which
-allow to specify the path of the ip-up and ip-down scripts to call.
-
-These options default to _PATH_IPUP and _PATH_IPDOWN to retain the 
-existing behaviour.
-
-The patch originated from the Debian project.

-pppd: Close already open ppp descriptors
-
-When using the kernel PPPoE driver in conjunction with the "persist" option,
-the already open descriptor to /dev/ppp is not closed when the link is
-reestablished. This eventually leads to high CPU load because the stray 
-descriptors are always reported as ready by select().
-
-This patch closes the descriptor if it is already open when establishing a
-new connection. It originated from the Debian project.

-pppd: Allow specifying ipv6-up and ipv6-down scripts
-
-This patch implements the "ipv6-up-script" and "ipv6-down-script" options
-which allow to specify the path of the ipv6-up and ipv6-down scripts to call.
-
-These options default to _PATH_IPV6UP and _PATH_IPV6DOWN to retain the
-existing behaviour.
-
-The patch originated from the Debian project.

-pppd: Watch out for time warps
-
-On many embedded systems there is no battery backed RTC and a proper system
-time only becomes available through NTP after establishing a connection.
-
-When the clock suddenly jumps forward, the internal accounting (connect time)
-is confused resulting in unreliable data.
-
-This patch implements periodic clock checking to look for time warps, if one
-is detected, the internal counters are adjusted accordingly.

-pppd: Retain foreign default routes on Linux
-
-On Linux, when pppd attempts to delete its default route it does not fill
-the rt_dev field of the struct rtentry used to match the system default route.
-As a consequence, pppd happily deletes any default route even if it belongs
-to another interface.
-
-This patch makes pppd fill out the rt_dev field so that only own default
-routes are ever matched.

-pppd: Fill in default gateway on Linux
-
-On Linux, when pppd creates the default route, it does not set the peer

-pppd: Support "nomp" option even if multilink support is off

-This patch moves the "nomp" option entry outside of the defines protecting
-the multilink specific code. The motivation is to allow "nomp" even if pppd
-does not support multilink, so that controlling programs can unconditionally
-pass it to pppd regardless of the compile time features.

-+.SH NAME
-+pptp.so \- PPTP VPN plugin for
-+.BR pppd (8)
-+.SH SYNOPSIS
-+.B pppd
-+[
-+.I options
-+]
-+plugin pptp.so
-+.SH DESCRIPTION
-+.LP
-+The PPTP plugin for pppd performs interaction with pptp kernel module
-+and has built-in call manager (client part of PPTP).
-+It pasees necessary paremeters from \fIoptions\fR into kernel module 
-+to configure ppp-pptp channel. If it runs in client mode, then additionally 
-+call manager starts up. PPTPD daemon automaticaly invokes this plugin
-+in server mode and passes necessary options, so additional configuration
-+is not needed.
-+
-+.SH OPTIONS for client mode
-+The PPTP plugin introduces one additional pppd option:
-+.TP
-+.BI "pptp_server " server " (required)"
-+Specifies ip address or hostname of pptp server.
-+.TP
-+.BI "pptp_window " packets " (optional)"
-+The amount of sliding window size. 
-+Set to 0 to turn off sliding window.
-+    to 3-10 for low speed connections.
-+    to >10 for hi speed connections.
-+Default is 50
-+.TP
-+.BI "pptp_phone " phone " (optional)"
-+The phone string that sended to pptp server.
-+.SH USAGE
-+Sample configuration file:
-+.nf
-+plugin "pptp.so"
-+pptp_server 192.168.0.1
-+pptp_window 100
-+name myname
-+remotename pptp
