A long-standing Wish (and Grumble) has been addressed. Thanks,

-------- update 12jul2007


      1.  arch now allows you to fit models assuming that the
disturbances follow Student's
          t distribution or the generalized error distribution, as
well as the Gaussian
          (normal) distribution.  Specify which distribution to use
with the distribution()
          option.  You can specify the shape or degree-of-freedom
parameter, or you can let
          arch estimate it along with the other parameters of the model.
