Comparing to JSON-RPC, ZMQ also support local or remote TCP request (and many
more mechanisms like PGM, IPC and In-proc). Argparse can provide a neat help
output and error handle interface, as well as support to subcommands.
ZMQ is preferred if you want to interact with this task from C++/Python/Java
or even command line. JSON-RPC is suitable for web users in case someone want
to control the task from webpage using JavaScript.
