  The fuzzers can be built locally if you have libFuzzer installed by running
  scripts/oss-fuzz.sh. You should also confirm that the fuzzer runs in the
 -OSS-Fuzz environment by checking out the OSS-Fuzz repo, modifying the git clone
 -in projects/systemd/Dockerfile to point at your code (for example, a fork on
 -GitHub) and then running these commands:
