The entries file records the sticky tag which can be either a tag or a 
date.  Currently no syntax exists to hold both at the same time.

There don't seem to be many actual checks to stop you doing it.. rtag is 
the only explicit one I could find - although it's possible I removed 
them sometime.. the code I work with is subsantially different to the 
cvsnt release.

For cvsnt I suspect it's too entrenched in the old code to make it work, 
although it's Arthur's call if he wants to do it.

In EVS as far as I can tell it'll just work anyway, since date is a 
separate attribute (and the entries file isn't used normally)... OTOH 
I've not had occasion to test that.

For that you would normally do a merge to remove changes from the 
interim period (or more often a diff followed possibly by a merge of the 
parts that don't work).  Indeed I have had occasion to  do this.. it's 
easy to break things and need to roll back a change or two.
