+define Package/wshaper/description
+ A script to do traffing shaping with the HTB algorithm.
+ Wshaper attempts to:
+ * Maintain low latency for interfactive traffic at all times 
+ * Allow 'surfing' at reasonable speeds while up or downloading
+ * Make sure uploads don't harm downloads, and the other way around
