Conversion Problem

[Eric Katherman]

I do have MS compiled with PROJ support and am using mapscript.  Could you
give me a quick example as to how I go about using the minlon minlat.... in a
one or two line statement. Is it a class item or is it something I would put
in my mapfile? I haven't found anything about it under the mapscript docs
yet.
