Protocol Buffers are a way of encoding structured data in an
efficient yet extensible format. Google uses Protocol Buffers for almost all
of its internal 'RPC' protocols and file formats.  Additional documentation
is available in two included vignettes one of which corresponds to our 'JSS'
paper (2016, <doi:10.18637/jss.v071.i02>. A sufficiently recent version of
'Protocol Buffers' library is required; currently version 3.3.0 from 2017
is the stated minimum.
ProtoBuf libraries and compiler version 3.3.0 or
later; On Debian/Ubuntu these can be installed as
libprotoc-dev, libprotobuf-dev and protobuf-compiler, while on
Fedora/CentOS protobuf-devel and protobuf-compiler are needed.

A C++17 compiler is required as well.
