+//
+// Then build the testing package:
+// `go-fuzz-build github.com/pion/webrtc`
+//
+// And run the fuzzer on the corpus:
+// ```
+// mkdir workdir
+//
+// # optionally add a starter corpus of valid rtcp packets.
+// # the corpus should be as compact and diverse as possible.
+// cp -r ~/my-rtcp-packets workdir/corpus
+//
+// go-fuzz -bin=ase-fuzz.zip -workdir=workdir
