What am I cvsup-ing, when I use:

   *default release=cvs tag=.

The manual says about this
  .  "The main branch (the `current' release). This is the default,
      if only the date keyword is given."

But what is 'current'? Is that 5.2 at the moment? Or 4.8-current for me?
(my FreeBSD version is 4.8).

Thanks,
Rob.
