%description
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.
