	You write a little script that runs from the top of the directory. 
You feed the script the names of the tags that you want to find.  It 
runs `cvs log` on every file in the tree, looking for the tags.  If it 
finds one match, it saves that filename and revision number.  If it 
finds multiple matches, it uses the highest numbered revision.  When 
it is done, it extracts all matching files and versions via `cvs 
checkout -r`.

	WARNING:  if a given change is applied to multiple branches with the 
same tag (e.g. your tag names are PR numbers), then the logic to find 
the right revision becomes nontrivial.
