%description
Pure C++ implementations for reading and writing several common data
formats based on Google protocol-buffers. Currently supports 'rexp.proto'
for serialized R objects, 'geobuf.proto' for binary geojson, and
'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 '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.
