Hi to everybody I'm currently working to an another GUI to Ifeffit, aimed to large dataset , it is still in beta version and full of bug but some collaborators start to use it . In the installer that I send to them is present the "feff6l.exe" file, to generates phase and amplitudes , but now I have a doubt. Does the feff6l licence allows a generic redistribution? , or have the Horae and the Sixpack packages a special agreement? Thanks in advance Carmelo
