[GSAS-II] roughness function

[afalent at gwdg.de]

Well, it might be a silly comment but if you have some older prm file you can always edit it by hand in any text editor. The format is very easy to understand.  It is not as nice and easy as in gsas but if you do not rubbish the formating you can quickly create any configuration you desire. 

Good luck :)
