This binary is intended for users who want to use Protocol Buffers in languages other than C++ but do not want to compile protoc themselves. To install, simply place this binary somewhere in your PATH. If you intend to use the included well known types then don't forget to copy the contents of the 'include' directory somewhere as well, for example into '/usr/local/include/'.
