+gen-unifi-cert.sh
+	1) Do initial cert generation:
+	
+		gen-unifi-cert.sh -e email@address.com -d unifi.somedomain.com -d unifi.someotherdomain.com
+		
+	2) Put in /etc/cron.weekly/renew-unifi-ssl if everything works okay:
+	
+		/path/to/script/gen-unifi-cert.sh -r -d unifi.somedomain.com -d unifi.someotherdomain.com
+		
+	3) Script will now run weekly and renew the certificate if necessary ( <30 days remain)
+		and restart unifi only if cert has been renewed.
