How to read what is here
These pages exist to explain a subject in general terms. It is not advice of any professional kind and takes no account of an individual reader's position.
Where links lead
A link may lead to a website someone else runs. What those websites publish, and how they treat visitors, is their responsibility and not this one's.
Mistakes and changes
Care goes into this material, and even so it carries no promise of being complete, current, or error-free. What is described here can change without this page changing with it.
Amendments
Should any of it change, the revised text replaces the old from the moment it is published on this page.
