[BAHASA INDONESIA DICTIONARY DATABASE CREATION]
The purpose of this script is to assist you
with creating the mySQL database for the
Bahasa Indonesia Dictionary.
This script assumes that you have MYSQL
installed and running on this system.
I've tried to make this script as portable
as possible. If for some reason this script
fails then you will have to create the
database manually. See documentation
for more details.
Please feel free to modify this script to best
fit your needs.
You can abort this script at any time by
pressing CTRL C.
