+or more network adapters.  It does so by using iproute's tc command, but
+greatly simplifies its operation.  Wonder Shaper was first released by Bert
+Hubert in 2002.  A subsequent release added a command-line interface.  Wonder
+Shaper makes use of tc's Hierarchical Token Bucket (HTB) queue, ensuring good
+bandwidth management on high speed (above ten megabits) links.")
