I have placed some source code in the incoming directory
on moon:
i.texture - calculate second-order texture statistics on
GRASS raster files (co-occurrence matrix approach)
s.to.dig - convert GRASS site file (in the "E|N|#n desc" form)
to GRASS dig_cat and dig_att files (shell script).
The texture code was hacked over the past two hours and could probably
use some testing (if anyone's interested).
Man pages are included for both. I hope someone finds these useful.
