R help - Sep 2005 - clustering: Multivariate t mixtures

Hi,
Before I write code to do it does anyone know of code for fitting
mixtures of multivariate-t distributions.
I can't use McLachan's EMMIX code because the license is "For non
commercial use only". 
I checked, mclust and flexmix but both only do Gaussian. 

Thanks
Nicholas

The Gaussian case is available in a pre-packaged function FLXmclust(),
but the flexmix framework is not limited to that case. There is a paper
which appeared in the Journal of Statistical Software
(http://www.jstatsoft.org/) that explains how to write new M-steps for
flexmix. It is also contained in the package as
  vignette("flexmix-intro")

Best,
Z
