// format to encode configuration parameters in a fuzzer file. To add a new
// configuration, define a tag, update |SetupTest| in fuzzer.h to parse it, and
// update |WriteSettings| in bssl_shim to serialize it. Finally, record
// transcripts from a test run, and use the BORINGSSL_FUZZER_DEBUG environment
// variable to confirm the transcripts are compatible.

// kDataTag denotes that the remainder of the input should be passed to the TLS
// stack.
