Although the latest releases of Doxygen claim better handling of Objective-C categories, it still seems to choke on categories in my source code. I'm wondering if someone has gotten it to document categories properly.

As an example, I have a category on NSString defined as:

@interface NSString (CCFExtensions)

with an interface file named NSString_CCFExtensions.h and implementation file NSString_CCFExtension.m

Doxygen will reference the file with the superclass; but none of the category methods are documented, despite seemingly valid doxygen syntax.

What is the correct source markup to get Objective-C categories working?
