There are a couple of us working on it.  We're both also radio amateurs, so
we hope to keep our work completly free--so it can be used in open standard
software for amateur radio--as well as whatever else people feel like using
it in.  Our code will make its way back into the main tree.

Jean-Marc,  all of your hard work in reducing memory footprint and CPU usage
is wonderful.  Thank you, very much.
