[Felix De Federico Mesa]

        Hello, I am interesting how to compiling XGRASS. I instaled GRASS
with the binary distribution, but it have not XGRASS. I have the source
code but I don't know how compile this. In the directory grass/src/XGRASS 
there are many directories. How can I compile this? Sorry by my level of 
english but I am spanish and I'm not very good with english.

        Thanks.

        Felix.
