vc-create-tag

vc-create-tag is an interactive autoloaded compiled Lisp function in `vc.el'.

It is bound to C-x v s, <menu-bar> <tools> <vc> <vc-create-tag>.

(vc-create-tag DIR NAME BRANCHP)

Descending recursively from DIR, make a tag called NAME.
For each registered file, the working revision becomes part of
the named configuration. If the prefix argument BRANCHP is
given, the tag is made as a new branch and the files are
checked out in that new branch.
