%description
Rserve acts as a socket server (TCP/IP or local sockets) which allows
binary requests to be sent to R. Every connection has a separate workspace
and working directory. Client-side implementations are available for
popular languages such as C/C++ and Java, allowing any application to use
facilities of R without the need of linking to R code. Rserve supports
remote connection, user authentication and file transfer. A simple R
client is included in this package as well. In addition, it can also act
as a secure WebSockets and HTTP/HTTPS server.
