-Format all sources and tests. <flags> are passed to `cargo clippy`.
+Runs clippy on all sources. <flags> are passed to `cargo clippy`.
./miri many-seeds <command>:
Runs <command> over and over again with different seeds for Miri. The MIRIFLAGS
variable is set to its original value appended with ` -Zmiri-seed=$SEED` for
many different seeds.
+./miri bench <benches>:
+Runs the benchmarks from bench-cargo-miri in hyperfine. hyperfine needs to be installed.
+<benches> can explicitly list the benchmarks to run; by default, all of them are run.
