Regrettably, you must hope in vain - the Link Include File currently
does produce parabolic chains, not catenaries.  However, I am currently
updating the file to properly produce the latter curves for the chain,
and also to allow more general linking between points and lists of
points (so not only hanging chains can be created).  My sincerest
apologies to those who expected a little more realism ... I'm working on
it!
