# 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.

END {

	printf "COMMIT TRANSACTION;";
}

# match ONLY lines that begin with 2 hex numbers, -, and another hex number
