How to use VC to delete a branch?

[Durand]

Hello:

I am wondering, in VC, how does one delete a branch, say after merging
a feature branch to the master branch?  I have checked the section
about VC in the Emacs manual, and found no related paragraphs.  Since
the manual states that the VC support for branches-related operations
is limited, I guess this is not implemented yet?  Or are there
separate manuals for VC that I am not aware of?

If I would like to implement this support, are there hints as to where
to start first?

This is my first post here.  Sorry if it is off-topic.
