Comment (by cmbarton):

 A further question about g.proj.

 If I enter g.proj proj4='+proj=utm +zone=12 +datum=nad27' datatrans=-1

 I get a list of potential datum transforms to pick from.

 If I enter g.proj proj4='+proj=utm +zone=12 +ellps=clark66' datatrans=-1
 (or ellipse parameters instead of clark66)

 I do not get a list of transforms. Is this because...

 1) transforms are not needed if an ellipse is specified
 2) there is a bug in g.proj
 3) something else also needs to be specified to trigger the list of
 transforms?
