[GRASS-dev] Topic oriented GRASS manual pages

Hi,

using the second keyword of each module, I have auto-generated
a topic oriented GRASS manual. I wrote a small shell script for this.

Draft version available at:
http://gis.cri.fmach.it/download/grass_html/topics.html

Try for example:
- classification
- hydrology
- statistics

The second keyword list should be carefully revisited (while not breaking
too many translations) to better group the commands. However, even
in the current state it will be useful.

PS: Likely it would be better to rewrite my shell script to Python. It could
then be run on the GRASS web site weekly.
