I very much expected to find "best practices" for extending modules, but I haven't.
 
Does anyone have any pointers to resources or advice?
 
It's great that Drupal itself is modular, but if I want to add a little something to a module that already does 90% of what I want, it seems there ought to be a standard way to do this without forking it.
 
Wrapping a module I can imagine how to do, and overriding or adding functions as needed, but it seems there could be a way to do this without having to define every function and pass it through.  At least I hope to find recommendations on how to do this.
 
Thanks for any help,
