Argh! rmver (see man page) ?
I would strongly advise against such an operation that cannot be undone (as I mention and describe in detail here , here or there ).
And rmver not possible in the CCRC client (even in the latest version 7.1.2).
What I usually do is graphically merge from version n-1 to version n to create version n + 1 with the right content.
