DESCRIPTION
       This module is based on g.gui.gcp, the GCP manager of GRASS GIS.	 It is
       part of i.ortho.photo suite.

       The aim of this module is to give absolute location values to the fidu-
       cial points present (in number of 4 or 8) in a scanned aerial photo.

       This is necessary as (manual) scanning  introduces  distortions,	 rota-
       tions and also may not be limited to scan the boundary of the photo it-
       self. It	is thus	necessary to give to each fiducial the	exact  coordi-
       nates  in  mm  as  given	 by the	aerial photographic instrument design,
       which is	unique per camera.

       This module requires you	to have	made a group with  your	 aerial	 photo
       (i.group),  a  camera description file (i.ortho.target) and use them to
       launch the module. Additional requirements are the order	of  rectifica-
       tion  (1	if no of Fiducials is 4, 2 if no of Fiducials is 8) and	an ex-
       tension file (if	not given, defaults to \$filename_ip2i_out)

       An example for Location imagery60:
       g.gui.photo2image group=aerial@PERMANENT	raster=gs13.1@PERMANENT	camera=gscamera	order=2	extension=try --o
