Detecting current build definition

[Anders Sveen]

I have a custom notifier which is switching on and off some lava lamps. It is 
working out pretty good, but now I need to perform a different action depending 
on which build definition that fails/succeeds. So in short:
 
I have one project and two build definitions. How do I detect which build 
definition is triggered in my notifier?
 
 
 
 
Thanks,
Anders,
