     The relevant section of the GPG manual says:

    TRUST VALUES
           Trust  values  are used to indicate ownertrust and validity of keys and
           user IDs.  They are displayed with letters or strings:

           -      unknown No ownertrust assigned / not yet calculated.

           e      expired

                  Trust calculation has failed; probably due to an expired key.

           q      undefined, undef Not enough information for calculation.

           n      never Never trust this key.

           m      marginal Marginally trusted.

           f      full Fully trusted.

           u      ultimate Ultimately trusted.

           r      revoked For validity only: the key  or  the  user  ID  has  been
                  revoked.

           ?      err The program encountered an unknown trust value.

Thanks for finding that.  I would not have had an easy time finding it
myself.

That is too vague to be helpful.  It tells the reader to search for
some other publication, and doesn't even say precisely what
publication or what its name is -- let alone where to look.

I don't think I could have got anywhere from it.


I think we should include a cleaned-up and clarified version of this
table in those two commands' doc strings.

But we need to fill in some gaps.  From that text, it is not clear
what q means.  Also, it is oriented towards answering the question
"what does the trust calculation do with this key" rather than "what
is the status of this key".

GNU documentation should try to be _helpful_ and present material in
terms of what the user wants to know.

Attempting to convert the list above into practical meanings for
a user, here's my draft for an improved table.

           e      key has expired
           r      Key has been revoked.

           How much trust to put in signatures of other keys by this one:
           n      none
           m      marginal trust
           f      full trust (for instance, you signed this key)
           u      ultimate trust

[I don't entirely understand those.  I do not understand GPG's trust
facilities, I don't want to learn to understand them; what I really
want to know is whether I signed that key.  How can I tell that?]

           ?      inconsistency in key ring trust data
	   q      some other strange case

[What does that really mean?  How does q differ from hyphen?]

Can anyone clear up the unclear points?
