# This AWK script takes the IEEE's oui.txt file and creates insert
# statements to populate a SQL table with the following attributes:
# create table oui (
# oui macaddr primary key,
# manufacturer text);
# the table name is set by setting the AWK variable TABLE
#
# we translate the character apostrophe (') to double apostrophe ('') inside
# the company name to avoid SQL errors.
