New application XGAUFIT
                     =======================

XGAUFIT is a new program for fitting parameters of Gauss functions, 
Gauss-Hermite polynomials and Voigt line-shapes to data from a GIPSY set.
It replaces the older program GAUFIT. 

XGAUFIT has a graphical interface and has improved algorithms for calculating 
initial estimates and least squares fitting. 
The interactive version of XGAUFIT is called XGAUPROF.
