Lock a tree read-only for historical purposes

[Vicki Brown]

Is there any way with CVS to lock a tree so that no additional changes can be
checked in for files on that tree?

Specifically, lets say I have a tree of files for an "old" project. The
project is closed. If anyone plans to revive something from that project they
should make a copy into a new tree and start from there. But I don't just
want to clear out the old tree. I'd like to preserve the history but do so in
a read-only state. I want to set this part of my tree in amber.

Can I do that?
