[GRASSLIST:1940] GRASS 5 environment variables online

[Markus Neteler]

Hi all,

as the GRASS environment variables are of wide interest, I have
put them online:

http://www.geog.uni-hannover.de/grass/gdp/html_grass5/index.html
-> GRASS 5 Environment variables

This file is still under construction. Developers may add missing
explanations in source code at:
 html/env_vars.html

(was documents/envVars.txt before)

The web file is updated overnight automagically.

Regards

 Markus Neteler
