( #3333=superdoc: print w/ replies, xml ) Need Help??

I'm interested in what subroutine commenting practices people use. I'm not interested in figuring out which is the "best", just wonder methods others use...

When I create a module, before each private subroutine I put a comment like so:

## ## user_address() ## ## Arguments: ## $name: string Name of the user ## $phone: string Phone num of user ## ## Returns: string Address of user ## ## Does a database check on the given user and returns ## the address. ## sub user_address { #whatever }

I always use empty parentheses on the top line, just to make it obvious from a glance that this block of comments documents a subroutine.

Also, whenever I have a subroutine that will be called from outside the module, I use POD, like so:

=item population() Arguments: $country: string Country code of country Returns: integer Population of country Given a country, returns the population. =cut sub population { ...

My question: what do you do? I've seen a few varying styles in CPAN documentation... is there one style that you've found particularily useful, and why?
