Hello Martin,

first thanks for looking into this.  But I am afraid I have to answer "no"
to your question, i.e. no "slynx" in the *Help* produced but
ess-customize-alist.  Here is the content of this buffer.  I searched one
more time for the words "help" and "slynx" in my .emacs file but there is
no reference to them in there.

Hope you can make sense of this,

Gérald
