Script to generate GRASS location from outside GRASS
from GIS file (e.g. geoTIFF or SHAPE), wktfile or EPSG code.

TODO: rewrite as Python script. A partial solution is
implementedin GRASS 7:

* grass.create_location() [1] for unprojected locations, 
  for the rest is needed running GRASS session (`g.proj`).
