Problem with the Anonymous CVS instructions?

[George V. Neville-Neil]

Hi,

	I'm setting myself up for anonymous CVS, and I found the following
problem with the instructions (or with my understanding of them).

The web page (http://www.pdos.lcs.mit.edu/click/anoncvs.html) says this:


To update a previously checked out source tree, change into the click 
directory and run this command:

       % cvs -z5 up -dP


but this doesn't work on my system (FreeBSD 4.2).  What does work is:

cvs -z5 -d :pserver:clickcvs at butt.lcs.mit.edu:/cvs update

or at least seems to.  There is nothing to update as yet of course.  I'm just 
writing
a nightly download script.

Any clues?  Is the page wrong, am I?

Thanks,
George
