improve example, list requirements

[mark-pictor-csec]

It'd be nice to have a complete use example that can be copied and pasted. The current example has some commands that need to run within the fuzz_ng/ dir and some without.

I'd also like a list of required tools/libs and their versions. For example, something like

• requires protoc >= v1.2.3 from http://example.com/protoc
• requires libFuzzer from
• requires a C++ compiler
  • known to work with clang >= v4.5.6
  • known to work with gcc <= v2.72
• requires go >=v1.17.0 from

Also, why is go114-fuzz-build named such? Until I noticed the go.mod I assumed the tool must be limited to features available in go1.14. It might be worthwhile to rename this.
