except instead of compiling using GN targets, the build.sh script compiles the fuzz executables
directly.
### OSS-Fuzz dashboard
<https://oss-fuzz.com/fuzzer-stats> is useful to see metrics on how our fuzzers are running. It
shows things like executions per second (higher is better), edge coverage percent per fuzzer,
what percent of fuzzing runs end in OOM/timeout/crash, the entire corpus of fuzzed inputs
(corpus_backup), etc. Contact aarya@ to get permission to view this dashboard if necessary.

That dashboard also has a Coverage Report. Even though it appears the Coverage report is per fuzzer,
the reports always show the aggregated coverage from all fuzzers.
