// Fuzz implements a randomized fuzz test of the sdp
// parser using go-fuzz.
//
// To run the fuzzer, first download go-fuzz:
// `go get github.com/dvyukov/go-fuzz/...`
//
// Then build the testing package:
// `go-fuzz-build`
//
// And run the fuzzer on the corpus:
// `go-fuzz`

// It'd be nice to check that if we round trip Marshal then Unmarshal,
// we get the original back. Right now, though, we frequently don't,
// and we'd need to fix that first.
