This directory contains tools to create a mapping table from MAC addresses (e.g., Ethernet hardware addresses) to human-readable manufacturer strings. The `createoui' script builds the table structure, `updateoui' obtains the current official mapping table from the web site of the IEEE, converts it, and stores it in the database, `dropoui' removes everything. Use the --help option to get more usage information from the respective script. All three use the psql program; any extra arguments will be passed to psql.
