+ZeroTier One allows systems to join and participate in ZeroTier
+virtual networks.
+
+ZeroTier One is a client application that enables devices to join
+ZeroTier virtual networks (typically configured and managed by a
+network controller). It provides an encrypted and secure network
+connectivity solution that can be used for a variety of purposes,
+including VPN alternatives, remote access, distributed
+applications, and more.
+
+Since zerotier-one needs the tun module to be loaded in order to
+work, that is done in the start function of rc.zerotier-one.
+If you wish you can make the module load from rc.modules.local.
+
+The following can be used to start/stop NordVPN automatically:
+/etc/rc.d/rc.local
+
+  if [ -x /etc/rc.d/rc.zerotier-one ]; then
+    /etc/rc.d/rc.zerotier-one start
+  fi
+
+/etc/rc.d/rc.local_shutdown
+  if [ -x /etc/rc.d/rc.zerotier-one ]; then
+    /etc/rc.d/rc.zerotier-one stop
+  fi

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in. You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
