Hm. There used to be a comment in a (now deleted) document named
Documentation/kernel-doc-nano-HOWTO.txt about how to test kernel-doc.

I took that comment and made a script from it.
I'll attach the script. It's easy to use, but it is made to test only
one function or struct or union or enum at a time.

You need to have a script named 'kernel-doc' in your PATH or you can
specify where the script is located by using
$ KERNDOC=path/to/scripts/kernel-doc kdoc_function _parameters_

Its usage is:
kdoc_function filename funcname [text|man|html|docbook|xml]

where funcname can be a function, struct, union, or enum name.
The output format can be any of those listed, but the default is "text".

Let me know if you have any questions or problems.
