The shipper's default mode of operation is to expect to be started by the agent, expecting to be passed the address of the agent control protocol server to connect to. The control protocol is then responsible for sending the shipper it's runtime configuration.

To make local development and testing easier, allow the shipper to run in a standalone mode independent of the agent. Add a new command line flag that causes the shipper to read its configuration file from disk and start without waiting to connect to the agent control protocol server.
