DIGITAL ORTHO PHOTOS

  After bringing up Grass4.1 -> g.manual -> list ...
I find there are some interesting programs which I can't seem to find
on the moon tree. Anyone know of the source or binary forms of the
following:
  ortho.image-rectify
  ortho.image_to_photo
  ortho.initialize_exposure
  ortho.photo_to_target
  ortho.select_camera

  We are thinking of developing some of our own DOQ's with
these programs.
