A CVS question

[Mojahedul Hoque Abul Hasanat]

I am new to CVS. I committed a few changes. Now I want to revert the
changes and go back to a tagged revision. Of course I can checkout that
release and work on it. But what I want is to rollback the commits, and
bring the repository to the previous state.

In other words, I want to remove any changes in the repository after that
tag. Is this possible?

Many thanks in advance.
