  * NOTES
  *	  See acl.h.
  *
- *	  The xxx_aclmask() functions in this file are wrappers around
- *	  acl.c's aclmask() function; see that for basic usage information.
- *	  The wrapper functions add object-type-specific lookup capability.
- *	  Generally, they will throw error if the object doesn't exist.
- *
- *	  The xxx_aclmask_ext() functions add the ability to not throw
- *	  error if the object doesn't exist.  If their "is_missing" argument
- *	  isn't NULL, then when the object isn't found they will set
- *	  *is_missing = true and return zero (no privileges) instead of
- *	  throwing an error.  Caller must initialize *is_missing = false.
- *
- *	  The xxx_aclcheck() functions are simplified wrappers around the
- *	  corresponding xxx_aclmask() functions, simply returning ACLCHECK_OK
- *	  if any of the privileges specified in "mode" are held, and otherwise
- *	  a suitable error code (in practice, always ACLCHECK_NO_PRIV).
- *	  Again, they will throw error if the object doesn't exist.
- *
- *	  The xxx_aclcheck_ext() functions add the ability to not throw
- *	  error if the object doesn't exist.  Their "is_missing" argument
- *	  works similarly to the xxx_aclmask_ext() functions.
