The build.xml is a Apache Ant make file that will allow you to easily compile, run and package jMemorize. You can also import the project into Eclipse.

To use it in Eclipse:

1. Unpack the source
2. In Eclipse 3.2, File->New->Project->Create Java Project from an Ant Buildfile
3. If you see build errors, change the compiler compliance level to 5.0
4. Right click on build.xml, Run As->Ant Build
5. Create a run target. Add bin in the project folder to the class path so that the properties file is found.

You can also just download the small Apache Ant software directly. See this page on how to run Ant from command line.

Important! You have to run the build.xml at least once to create all necessary files and to move the resources into the right directories. After having run the build.xml file once, you'll also be able to run jMemorize using the regual Eclipse Java starter.
