Too small permanent file space to co a project - again

Thanks, Spiro.

OK, I will not use watches.
In my proposed method, there are two checkouts, first to $HOME, then to 
scratch. In one way or another, the second 'cvs co' will need to know what 
branches/tags the first co referred to. Is there a "standard" method to 
accomplish this, or do I have to maintain my own administration file(s) in 
$HOME for this?
