Frank (and others),

  I've noticed that Proj4 seems to do NAD 27 / 84 datum
conversions, but I'm still a little lost on how to specify
the parameters on the command line, or drive Proj4 using
the function calls to do the datum conversion.

  I've looked thru the Proj4 doc and the ShapeLib contrib 
doc at the info there is on using Proj4 to do datum conversion.

  Is there any additional datum conversion info specific to Proj4?
