Hi,

I read a lot about the new node access system at Drupal 5, but I just can't understand how it works.

I've read those about 10 times and I still can't understand it:
http://api.drupal.org/api/HEAD/group/node_access
http://api.drupal.org/api/HEAD/file/developer/examples/node_access_examp...

Please refer me to some content about it, or please explain me how it works.

Thanks a lot,
Have a nice day.
