libprotobuf-c0 binary package in Ubuntu Trusty ppc64el

 Protocol buffers are a flexible, efficient, automated mechanism for
 serializing structured data – think XML, but smaller, faster, and
 simpler. You define how you want your data to be structured once, then
 you can use special generated source code to easily write and read your
 structured data to and from a variety of data streams and using a variety
 of languages. You can even update your data structure without breaking
 deployed programs that are compiled against the "old" format.
 .
 This is the C implementation of protocol buffers.
 .
 This package contains the shared library.
