+### this file defines whether vtund is run as a client or a server
+###
+### format is "[host] [server] <args>" or "--server-- [portnumber] <args>".
+###
+### [host] is the hostname to use as a client
+###
+### [server] is the server to connect to
+###
+### [args] is optional for both server and client and contains any additional
+### command line args for that instance of vtund.  not needed by most people.
+###
+### --server-- is the literal string '--server--'. nothing more, nothing less.
+###
+### [portnumber] is the port number to run the server on.
+### 
+###
+### you can have more than one client "host server" line if required,
+### and in theory, it should be possible to run as both a client and a
+### server simultaneously, but i haven't tested that.
+
+
+### examples:
+
+### to run as a client using hostname 'viper'.
+#viper vtun-server.somewhere.com.au
+
+### to run a persistent client connection using hostname 'viper'
+### connecting to a server on port 6000 and using /etc/vtun.viper.conf
+### as the config file.
+#viper vtun-server.somewhere.com.au -f /etc/vtun.viper.conf -s -P 6000
+
+### to run vtund as a server on port 5000, uncomment the following line:
+#--server-- 5000
