This document describes how to create a simple HL7 Sender and Receiver project.

The HL7 Sender project polls for files on a file system containing HL7 messages and sends them over MLLP to an HL7 external using the HL7 Outbound port and then writes the acknowledgement back to the file system.
The HL7 Consumer (Receiver) project connects up the HL7 interface over MLLP (port 4040) and receives the HL7 messages, converts to XML and writes the data out to a file in XML format.
