 # Language Bindings
 [Language bindings](https://en.wikipedia.org/wiki/Language_binding) refers to wrappers to bridge 2 programming languages. This is used in P2PRC to extend calling P2PRC functions in other programming languages. Currently this is done by generating ```.so``` and ```.h``` from the Go compiler.
