To be precise: If GRASS is started for the first time in "-text"
mode
(=no GUI) ** without having a sample location like Spearfish or
North
Carolina around**, how can location parameters (projection,
extent,
EPSG...) be handed over to set up a very first location ?
Just type in the name of the location you want to create and
GRASS will
prompt you for the parameters.
That's true. But is there also a way to provide the parameters
_without_ interaction with the user (-> GRASS scripting &
automation)
You can create a new location and mapset with "g.proj -c ...", then
make it current with g.mapset. But those are GRASS commands, and only
work within GRASS.
I imagine that you can create your own location by having a script
create the location directory, the PERMANENT mapset directory and the
PROJ_INFO, DEFAULT_WIND and PROJ_UNITS files, or ?

AFAICT, you'll need to script this, since you can't run GRASS commands
to create a location until you've started GRASS in a location.
We are switching GRASS to primarily use Python for scripting (though
it will always be possible to use other languages). Check out the new
Python location wizard for code to create locations before starting
GRASS. ../gui/wxpythyon/gui_modules/location_wizard.py
