+ * This is the netconf service. It's currently used only by netconf nodes that
+ * are run by ZeroTier itself. There is nothing to prevent you from running
+ * your own if you wanted to create your own networks outside our system.
+ *
+ * That being said, we'd like to charge for private networks to support
+ * ZeroTier One and future development efforts. So while this software is
+ * open source and we're not going to stop you from sidestepping this, we
+ * do ask -- honor system here -- that you pay for private networks if you
+ * are going to use them for any commercial purpose such as a business VPN
+ * alternative.
+ *
+ * This will at the moment only build on Linux and requires the mysql++
+ * library, which is available here:
+ *
+ * http://tangentsoft.net/mysql++/
+ *
+ * (Packages are available for CentOS via EPEL and for any Debian distro.)
+ *
+ * This program must be built and installed in the services.d subfolder of
+ * the ZeroTier One home folder of the node designated to act as a master
+ * for networks. Doing so will enable the NETWORK_CONFIG_REQUEST protocol
+ * verb.
