I'm guessing that ConvertCoordinateSystemCodeToWkt is what MapGuide uses
to generate the WKT that is stored in the repository.  

To get the PROJ.4 WKT stored by MapGuide, can I just run
EnumerateCategories then EnumerateCoordinateSystems and
ConvertCoordinateSystemCodeToWkt against the current MapGuide Open
Source?

If so, the results (pipe-delimited, code|WKT) are available in this
file:

I've attached the script I used to generate this, which needs to be
placed in the mapagent directory to run.

The other alternative (bare metal PROJ.4 APIs) isn't all that
approachable for me :)
