Thank you for this Tyler,
Will certainly take it for a spin.
I've been using spgrass6 and ESS for a while.
Cheers,

Glad to hear it! It wil also work for commands that import maps from other 
locations. E.g., v.proj - after you've entered the 'location' value, it will 
use that directory to complete the 'input' map name.

These little tweaks are not automatic - I have to add a line for each case. So 
if you find something that isn't completing as it should, let me know.

Best,

Tyler

autocompletion of map names is by far the most welcoming feature!

I added recently a module r.skyview to grass 7 addons  for computing the
sky-view factor [1]. It uses r.horizon module.  I am not sure how much
different is what r.horizon can do and what you need but it's worth looking
if r.horizon cannot be extended easily and then used for the openness
computation.

Rebecca,

I recall there was some capability w/in GRASS previously with terrain
analysis, with classification of landform types -- but not using this
nomenclature. Types were: slope, valley, ridge, saddle, etc... There may
have been 'kettle' and 'dome' which seem to be close to your + and -
openness. I can't remember the module. I know I have some F77 code buried
away someplace written by a teacher years ago during my undergrad days
taking geomorphology

Hi Lars,

after we fixed to integrate the g.html2man script to the grass package, it
is now no longer possible to install the grass package itself, without
manually ignoring this error:

failed on file /opt/grass/tools/g.html2man: cpio: rename failed - Is a
directory error: grass-6.4.3-4.4.x86_64: install failed error:
grass-6.4.3-3.19.x86_64: erase skipped

We haven't found a solution to fix this yet, and because many people
recently complained, that grass can't be updated/installed automatically, we
decided to revert the g.html2man fix for now.

We will build and integrate the g.html2man script to the grass package
again, once we find a solution for the error above. 

Regards
Otto
