> Q: Why do I need this package?
A: It helps if you want to deploy pre-compiled software to use in Lambda. See list of projects where it is used above.
> Q: Why bother?
A: Lambda environment has limited software installed. This package helps ship large binaries compiled for Lambda
which unpack to /tmp folder when Lambda starts.
> Q: Why /tmp?
A: Lambda has 500 MB of storage in /tmp
> Q: Why brotli?
A: This compression algorithm is known for great speed/size ration. Perfect for scarce Lambda resources.
