As described by Apple:
The EPFImporter is a command-line based tool, available to EPF partners, that allows for ingestion of the EPF-Relational files into a relational database. The tool is written in Python and the source code is available for modification by partners to fit their specific needs and platform.

This version has been modified to run cleanly with MySQL 5.6 and the EPF data as provided by Apple in 2014.
