[Gvsig_english] Sextante extension question

[Guillermo Tamburini]

Hi David,

ok, I have understood what you want to do. I'm sorry but for the moment 
I will not be able to help you. As I said you, as gvSIG users list, may 
be it will be a little bit difficult to get always responses to the 
doubts in Sextante tools. I'm not sure if exists a Sextante users list.

However if I find the form to resolve that trouble, I will say you, or 
maybe somebody else could help us with that.

Salud and luck!
