Policy on @author?

[Andy Seaborne]

Do we want a policy about @author tags and other comment metadata about 
authorship?

Personally, I'd like to see none at all - they age badly and maybe they 
put off outside contributors to the code.

(I've just been in some very old code and while it's an interesting 
history exercise, it's not very useful.  I have some time ago removed 
any @author with my name on in ARQ, TDB etc.)

Thoughts?
