+# In the source location, use v.in.region to generate a bounding box around the
+# region of interest:

+v.in.region output=bounds type=area
+
+# Now switch to the target location and import the vector bounding box 
+# (you can run v.proj -l to get a list of vector maps in the source location):

+v.proj input=bounds location=source_location_name output=bounds_reprojected

+# Set the region in the target location with that of the newly-imported vector
+# bounds map, and align the resolution to the desired cell resolution of the 
+# final, reprojected raster map:
