Add one more sentence to end the abstract by describing what the paper
is about:

"This paper outlines the general class of data serialization
requirements for statistical computing, describes the implementation
of the \CRANpkg{RProtoBuf} package, and illustrates its use with
examples applications in large-scale data collection pipelines and web
services."

We still have the nice page break between pages 2 and 3 where section
2 begins at the very top of page 3.
