Expected output from Trace and from emitObfuscatedFiles options?

I've added the `trace` option to my configuration to help me determine why the output doesn't seem to be transformed at all, but I've not been able to determine where I should see this output. It doesn't appear in my console.

I haven't been able to find any output files anywhere either. Where would one expect to find those?

Thanks for any advice!

`trace` と `emitObfuscatedFiles` の設定オプションを確認し、この transformer がコンソール出力を報告し、ファイルを書き込む場所を特定してください。React Native ユーザー向けに、想定される出力先と動作が文書化されていれば完了です。
