First, we don't advocate editing bundles, because you can really
shoot yourself in the foot if you change/delete the wrong thing.

><property name="Name">

The file name is going to be relative to the process that starts the
IDV, not the bundle.  So, if you have the IDV on the CD, make sure
the script that runs it cd's to the directory where the data and
bundle are:

cd ../data
../IDV1_2/jre/java -Xmx512m -jar ../IDV1_2/idv.jar


or something like that.

We'll think about ways to make this easier for the future.
