Protobuf

For convenience, the smithy4s build plugins generate protobuf (.proto) definitions translated from smithy specifications out of the box. However, this translation is limited to the transitive closure of shapes that have the alloy.proto#protoEnabled or the alloy.proto#grpc traits.

The location of these protobuf specifications is driven by the smithy4sResourceDir setting in SBT and the smithy4sResourceOutputDir in mill.

The semantics of the smithy to protobuf translation are following the alloy specification.
