-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.
