HELP = '''
|
|
Provide a shell used to send interactive commands to a zmq filter.
|
|
|
|
The command assumes there is a running zmq or azmq filter acting as a
|
|
ZMQ server.
|
|
|
|
You can send a command to it, follwing the syntax:
|
|
TARGET COMMAND [COMMAND_ARGS]
|
|
|
|
* TARGET is the target filter identifier to send the command to
|
|
* COMMAND is the name of the command sent to the filter
|
|
* COMMAND_ARGS is the optional specification of command arguments
|
|
|
|
See the zmq/azmq filters documentation for more details, and the
|
|
zeromq documentation at:
