Maybe we should mention that method at the beginning of the list of
priority strings?

I think an auto-generated appendix would be terrific as a reference, so
you don't have to run gnutls-cli to find out what "NORMAL" means.  For
instance, if you're setting up priority strings in Emacs, it would be
really nice :)  It sounds reasonably easy with some scripting.  As text
it would be very convenient for grepping and diffing.

The meaning of e.g. "NORMAL" for a particular release is particularly
important, both to look for behavior changes as a diff and for users
stuck on that release.

Understood, it's a hassle certainly.

What do you think about this?
