How does bpVMreq cmd collect vCloud metadata?

Hello,

Can someone please tell me what is inside bpVMreq command and how the metadata for vCloud infrastructure is collected?

Is it a vCloud API call or some other way? If its API call, which is it?

We have Veritas enhancement request open and im trying to assist as much as possible, and this piece of information could lead to a successful solution.

Thanks for any kind of help.
