I didn't know about the Drupalcontrib API docs, but I did know about the
Lullabot API site. I had checked the Lullabot site, and found nothing. I just
now checked the Drupalcontrib site, and it's not there, either.
The problem is, that the hooks are not defined by Drupal, and they are not
themselves functions (so have no doxygen comments). So, if you search for
"hook_content_extra_fields," you will find nothing at either site.
This is not a knock at either site (both of which are excellent), it's
something that really should have been a tutorial from the CCK authors
themselves. I'm surprised it's not in the handbook.
I'm also really surprised it's not in the node_example module. It really should
be. Maybe I'll raise this as an issue in the queue?
