Provides low-level socket and protocol support for handling HTTP and
WebSocket requests directly from within R. It is primarily intended as
a building block for other packages, rather than making it
particularly easy to create complete web applications using httpuv
alone. httpuv is built on top of the libuv and http-parser C
libraries, both of which were developed by Joyent, Inc. (See LICENSE
file for libuv and http-parser license information.)
