+define Package/lldpd/description
+	LLDP (Link Layer Discovery Protocol) is an industry standard protocol designed 
+	to supplant proprietary Link-Layer protocols such as 
+	Extreme's EDP (Extreme Discovery Protocol) and 
+	CDP (Cisco Discovery Protocol). 
+	The goal of LLDP is to provide an inter-vendor compatible mechanism to deliver 
+	Link-Layer notifications to adjacent network devices.
