%global _description %{expand:
Census provides a framework to define and collect stats against metrics and to
break those stats down across user-defined dimensions.

The Census framework is natively available in many languages (e.g. C++, Go, and
Java). The API interface types are defined using protos to ensure consistency
and interoperability for the different implementations.}
