A serialization format developed by Google and used widely within Google, and by numerous other projects. Quoting from the official website:
Protocol buffers are Google’s language-neutral, platform-neutral, extensible mechanism for serializing structured data – think XML, but smaller, faster, and simpler.

Under Debian/Ubuntu you may need

The package contains two pdf vignettes; the second one corresponds to our JSS paper.
