Hi, samdoyle. Thank you very much for your answer.
Thanks to your answer I've managed to find something else I was looking for, but I'm afraid this does not help me to solve my problem.
You see, what I want to do is create a linux-based appliance with vmware studio, and change the help.url property before the appliance is deployed.
Do you know where I have to go to change that parameter?
I also had a look on my vmware studio and my appliance and did not find the file "/opt/vmware/var/lib/build/services/core/<version>/view/view.xml".
none of them have a "core" folder. 
Thanks!
