[racket] DrRacket Plugins require drracket/too-lib alone seems to cause error

Hi,

'raco setup -l tool-name' fails for tools with only '(require
drracket/too-lib)' fails with an unknown signature error[1]

Requiring 'drracket/tool' resolves the error, but this doesn't match the
plugins documentation. (e.g.
http://download.racket-lang.org/docs/5.3.6/html/tools/ )

I don't know if this is a documentation error, a bug, or if I have just
mis-read the documentation.  I've included a sample of my code [2].

(provide tool@)

    (export drracket:tool-exports^)

Kind regards,
