Craig, et al,
It is my intention at some point to rip out all of the PROJ.4 core that
I am using and use Gerald's work instead. However, this is a substantial
job, and I'm not exactly sure when I will get to it. There are also
questions about what degree of backward compatibility with older
versions of PROJ.4 (4.4.x) will be achieved in this move. Whether I
move to a whole new API or what.
Best regards,
