+OpenVPN Plugins
+---------------
+
+Starting with OpenVPN 2.0-beta17, compiled plugin modules are
+supported on any *nix OS which includes libdl or on Windows.
+One or more modules may be loaded into OpenVPN using
+the --plugin directive, and each plugin module is capable of
+intercepting any of the script callbacks which OpenVPN supports:
+
+(1) up
+(2) down
+(3) route-up
+(4) ipchange
+(5) tls-verify
+(6) auth-user-pass-verify
+(7) client-connect
+(8) client-disconnect
+(9) learn-address
+
+See the openvpn-plugin.h file in the top-level directory of the
+OpenVPN source distribution for more detailed information
+on the plugin interface.
+
+Included Plugins
+----------------
+
+auth-pam -- Authenticate using PAM and a split privilege
+            execution model which functions even if
+            root privileges or the execution environment
+            have been altered with --user/--group/--chroot.
+            Tested on Linux only.
+
+down-root -- Enable the running of down scripts with root privileges
+             even if --user/--group/--chroot have been used
+             to drop root privileges or change the execution
+             environment.  Not applicable on Windows.
+
+examples -- A simple example that demonstrates a portable
+            plugin, i.e. one which can be built for *nix
+            or Windows from the same source.
+
+Building Plugins
+----------------
+
+cd to the top-level directory of a plugin, and use the
+"make" command to build it.  The examples plugin is
+built using a build script, not a makefile.

+Provide proxy server host/port and flags in response to a >PROXY
+notification (client only).  Requires that the --management-query-proxy
+directive is used.
+
+  proxy TYPE HOST PORT ["nct"]
+
+The "proxy" command must only be given in response to a >PROXY
+notification.  Use the "nct" flag if you only want to allow
+non-cleartext auth with the proxy server.  The following >PROXY
+notification indicates that the client config file would ordinarily
+connect to the first --remote configured, vpn.example.com using TCP:
+
+  >PROXY:1,TCP,vpn.example.com
+
+Now, suppose we want to connect to the remote host using the proxy server
+proxy.intranet port 8080 with secure authentication only, if required.
+After receiving the above notification, use this command:
+
+  proxy HTTP proxy.intranet 8080 nct
+
+You can also use the SOCKS keyword to pass a SOCKS server address, like:
+
+  proxy SOCKS fe00::1 1080
+
+To accept connecting to the host and port directly, use this command:
+
+  proxy NONE
