-  I had originally planned a high level, C++, object-oriented library for

-  However, C++ compilers are not available for some of the targets supported by NuttX.
-  So I have decided to implement the entire solution in  C.
-  That decision makes the solution somewhat more difficult to work with, but supports all platforms.
