Hi Markus,

Thanks very much for the quick response.

Guess I'll wait till the libraries are installed by the WinGRASS
maintainer. I suppose the reason I can't use i.spectral is the same,
although it is not an addon.

Would have loved to attend the meet in Italy, but I don't see a chance, as
I live in Canada. Thank you for adding it to the agenda though.
