-## RPC
-
-This package includes an RPC mechanism to remotely execute julia functions, possibly from different programming languages. The on-the-wire protocol used for passing messages is the standard Julia serialisation format built into the standard library. 
-
-As the functionality matures, this may be split into a separate package. 
-
-```julia
-require("ZMQ/src/RPCJuliaSer")
-using RPCJuliaSer
-run_server() #using port 5555 by default
-```
-
-In a separate Julia session
-```jlcon
-julia> require("ZMQ/src/RPCJuliaSer")
-
-julia> using RPCJuliaSer
-
-julia> ctx,req=launch_client()
-(ZMQContext(Ptr{Void} @0x0000000103b7a600),ZMQSocket(Ptr{Void} @0x0000000103b6e890))
-
-julia> zmqparse(req, "2+2")
