cvs -nq update -dP problem

Hi, I would really appreciate help with this:

"Using CVS to maintain a Drupal website" (http://drupal.org/node/93966) states the following:

cvs -nq update -dP

If updates are available, this will display output similar to:

U modules/taxonomy/taxonomy.module
U modules/upload/upload.module

The 'U' means that the listed file is newer, or "updated" from the one you have in your local copy.

However, the actual output that I get from this command is a listing of ALL Drupal modules and themes, not just the ones I am using. The output is 100's of lines long. Here is a snippet of the output:

cvs update: New directory `sites/all/modules/zencart' -- ignored
cvs update: New directory `sites/all/modules/zend' -- ignored
cvs update: New directory `sites/all/modules/zend_feed' -- ignored
cvs update: New directory `sites/all/modules/zendesk' -- ignored
cvs update: New directory `sites/all/modules/zenify' -- ignored
cvs update: New directory `sites/all/modules/zenophile' -- ignored
cvs update: New directory `sites/all/modules/zenophile_extras' -- ignore
cvs update: New directory `sites/all/modules/zensursula' -- ignored
cvs update: New directory `sites/all/modules/ziki' -- ignored
cvs update: New directory `sites/all/modules/zimbra' -- ignored
cvs update: New directory `sites/all/modules/zina' -- ignored
cvs update: New directory `sites/all/modules/zipcode' -- ignored

I am trying to learn and running cvs within cygwin on Windoze XP.

I have been studying CVS manuals but can't figure it out.

If someone could tell me what I am doing wrong, that would be much appreciated.

Thanks in advance for any help.
