+     "This package provides pure C++ implementations for reading and writing
+several common data formats based on Google protocol-buffers.  It currently
+supports @code{rexp.proto} for serialized R objects, @code{geobuf.proto} for
+binary geojson, and @code{mvt.proto} for vector tiles.  This package uses the
+auto-generated C++ code by protobuf-compiler, hence the entire serialization
+is optimized at compile time.  The @code{RProtoBuf} package on the other hand
+uses the protobuf runtime library to provide a general-purpose toolkit for
+reading and writing arbitrary protocol-buffer data in R.")
