To upgrade from Fruity 1.0 rc1, perform the following steps:

1) Backup your Fruity database (extremely important in case something goes wrong)

2) Modify the upgrade.php file to reflect your database connection parameters.  Be sure to 
specify a user which has ALTER,UPDATE,INSERT,CREATE rights to the Fruity database.

3) Run the upgrade.php script in your web-browser.

4) Once the upgrade is complete, remove the upgrade.php script, it is no longer needed.
