I added the script from Paolo/Perrygeo
1.35.1 Shapemerge -
5.1.35.1 Shapemerge - http://grass.osgeo.org/wiki/GRASS_AddOns
#Shapemerge
But I would like to see this integraded into GRASS...

What if you receive a location with 5 vectors and 10 rasters?
Since we are agreeing that GRASS has a strong script support one
could to something like this pseudo code:

### create_new_projected_location
grass_command_to_create_newlocation \
currentlocation_new_epsg_code 'EPSG:XXXX'
grass_command_enter_to_currentlocation_new_epsg_code
## in the new location:
for vect in currentlocation:
    v.proj in=vect out=vect location=currentlocation
for rast in currentlocation:
    r.proj ...
print "Please exit GRASS and enter the new reprojetced location
'currentlocation_new_epsg_code'."

I don't know if this is possible with grass scripting but would ease up
changing the projection.

Nice.
But please consider to assist the user in adjusting the g.region before
printing. My ps.map.def that I tested on spearfish doesn't work when
trying to print a raster of whole Europe. It results in a 4GB PS file although
I'd set the paper size.
