[exim] Documentation of tls_dhparam

Hi,

The documentation page of TLS configuration says this:

http://www.exim.org/exim-html-current/doc/html/spec_html/ch-encrypted_smtp_connections_using_tlsssl.html
> There are a few standard primes available, see the documentation for
> tls_dhparam for the complete list.

All I can find is the page that says this. So it must be the
documentation of tls_dhparam. But where did the author of that sentence
(it also appears further to the top of the page) think I should look for
more information?
