-1. Execute "go run roll_boringssl.go"
-2. Build and test Fuchsia as normal.
-3. Update //zircon/third_party/ulib/uboringssl as documented there.
-4. Commit and push normally.  Note the resulting revision for the next step.
-5. Create and upload a CL that updates //garnet/manifest/boringssl
+1. Make sure you have the Rust bindgen tool installed (at least version 0.37, https://github.com/rust-lang-nursery/rust-bindgen).
