VCS Simulator 7.0

Hello all.

VCS simulator has been around for quite a while and it is a really usefull tool both for testing cluster configuration files before put them in production and for DEMO purposes which is my case and that's why I'm writing this post.
Is there any user guide or document explaining how to use or how are configured the included cluster configuration examples? 
I've been able to understand some cluster examples and use some features, but some other cluster examples seem like some configuration is required to make them work but as there's no information (to my knowledge) on how they are configured, I haven't been able to find a way to make this cluster examples work.
Really appreciate any guidance that points my into the right direction.
