This directory contains all of the portal's database scripts. Read the Liferay Portal 4 - Installation Guide for more information about using them to prepare a database for Liferay Portal and to configure the application server being used to run against it.

There are also two files named test.properties and test.script that are copied over to your specified application server's bin directory when you run ant deploy from /ext. The two files are used by Hypersonic and contain a snapshot of the portal's default data.
