-grpc_logsettable contains a thread-safe wrapper around grpc-logging
-infrastructure.
-
-The go-grpc assumes that logger can be only configured once as the `SetLoggerV2`
-method is:
-```Not mutex-protected, should be called before any gRPC functions.```
-
-This package allows to supply parent logger once ("before any grpc"), but
-later change underlying implementation in thread-safe way when needed.
-
-It's in particular useful for testing, where each testcase might need its own
-logger.
