define Package/vnstat/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/vnstati/description
	The purpose of vnstati is to provide image output support for statistics
	collected using vnstat(1). 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.
