Thanks “nWill” for his kind comment on my previous post, I found a problem on “v0.2″ and in “v0.3″ I tried to fixed some problems previous script had such as not being able to work properly in environment with only one “Template, Customization Specification, Host, Resource Pool or vApp”.
I’ve added some description as well as defining some other condition but might still got some problem, so please let me know if you find any.
