### Description
The pprof tool defines a [protocol buffer](https://developers.google.com/protocol-buffers) output format, which is always stored with gzip compression and described in great detail this [README](https://github.com/google/pprof/blob/master/proto/README.md) as well as the [profile.proto](https://github.com/google/pprof/blob/master/proto/profile.proto) definition file itself.
