+endef
+
+define Package/vnstat2/description
+	vnStat is a network traffic monitor for Linux that keeps a log of daily
+	network traffic for the selected interface(s). vnStat isn't a packet
+	sniffer. The traffic information is analyzed from the /proc -filesystem,
+	so vnStat can be used without root permissions.

+  TITLE:=PNG image output support for vnStat
+endef
+
+define Package/vnstati2/description
+	The purpose of vnstati is to provide image output support for statistics
+	collected using vnstat. However, the image file format is limited to
+	png. All basic outputs of vnStat are supported excluding live traffic
+	features. The image can be outputted either to a file or to standard
+	output.
