New docs for OPTIONS

[Chris Rees]

Hi all,

We have a new world order for OPTIONS in ports (exciting, isn't it??),
and would very much like to document it.

I've prepared the following patch which has had fairly extensive
review, apart from not having a formal approval by a docs person.

Would anyone mind giving it a check and approving it please?  Bapt
plans to commit the code later this week, and it'd be great to have
approval by then!

Thanks,

Chris
