Sample userInputSpec.xml

Here's an example 3 panel userInputSpec.xml file. You specify the use of this XML document inside your install definition in the resource section like this (assuming your ant build.xml uses a property called build.dir):

<resources>
  <res id="userInputSpec.xml" src="@{build.dir}/userInputSpec.xml" />
</resources>
