postgres/contrib/mac

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.
