MySQL local script installer

Description

This is a small utility I made to import sql files to local MySQL 4.1 servers, as I have to do this on many machines. It's a stripped down version as others stuffs were too specifics to my needs but this version works fine too.

Basically, the script checks if no error is returned (like wrong password) and continues if it's ok.
