Steve's mostly got it here, except that 1.3.2 is a valid way of refering to a
branch _IN A SINGLE FILE_.  If you want to refer to a branch in multiple files
it's much easier to use a symbolic name.

Unfortunately the command Mark mentions still only creates a static tag
attached to 1.3.2.x, where 1.3.2.x is the revisionn on the tip of the 1.3.2

That's a carry over from RCS which CVS still supports.  1.3.2 is the numeric
"name" of the branch containing 1.3.2.x revisions - CVS would attach the tag to

cvs admin -n is the most reliable way I know.  Matthias seems to have been
correct that it doesn't work on files not checked out in the cwd.  Not even
when specified explicitly.

"My father often told me,
We have servants and machines
in order that our will may be carried out
beyond the reach of our own arms.
Machines are more powerful than servants
and more obedient and less rebellious,
but machines have no judgement
and will not remonstrate with us
when our will is foolish,
and will not disobey us
when our will is evil.
In times and places where people despise the gods,
those most in need of servants have machines,
or choose servants who will behave like machines.
I believe this will continue
until the gods stop laughing."
