You can hide any of:
1. the private part of a spec (not the visible part)
   the --# hide follows the 'private' keyword

2. a package body (all of it)
   the --# hide follows the 'is' keyword.

3. a subprogram body
   ditto

4. the initialisation part of a package body
   the --# hide follows the 'begin' keyword.

Cheers,
