[drupal-devel] Hook_settings() confusion

Resubmit your module enabling page (administer >> modules) or otherwise 
empty the cache, so that the menu gets regenerated. If you have a module 
without the settings hook enabled, and then replace the code under 
Drupal to something with the settings hook, it will not get into the 
menu, due to menu caching. Drupal expects no code changes in files 
unless you resubmit the module enabling page, or otherwise empty the cache.
