[GRASS-web] use of graphics in textbook

[Paul Bolstad]

Hello,
I'm working on a third edition of a general GIS textbook. I would like 
to include some graphics from your web pages in the book, fully 
acknowledged, in a discussion of open source GIS as a positive 
development for the future. Since it says copyright, developers, I would 
like permission to include some screen shots.  Please let me know if 
this is possible, and what I might do to facilitate this process.

Thanks,

Paul Bolstad
