[development] node type not listed at node/add

[augustin (beginner)]

Hello,

With a module implementing its own node type, the said node type is not listed 
at node/add.

Is this a feature or a bug?
http://drupal.org/node/368924

Everywhere, it is said that the menu item is automatically created from 
hook_node_info() but having read the documentation and followed the 
tutorials, it just doesn't work for me.


Thanks,

Augustin.
