New Revision: 42772

Modified:
   grass-addons/LandDyn/r.catchment.py/r.catchment.py
Log:
Added small code snippet to make sure that the grass python scripting libs can be found even if the module is called by an external process (e.g. our ABM model). Added -A and -i flags to an r.stats call to make sure key values comeout as a single integer value rather than a range of values.
