Similar to protocol buffers, cap'n proto is an efficient means of serializing structured data to be transferred across a network or written to disk. users write a cap'n proto definition file that drives a code generator, which in turn emits c++ code for encoding & decoding messages in the cap'n proto format.

in addition to being extremely fast, cap'n proto also smooths over some of the rougher aspects of protocol buffers & introduces a number of new features to boot.

this package contains the runtime libraries needed for c++ applications.
