I guess I didn't make myself clear why I used this as an example. How
many pieces of non-NCBI code out there that use the toolbox? It's a great
toolkit and runs on everything, but it is also a mountain to learn
and is not always internally consistent in its design.
My argument is that if it were in C++ rather than ANSI C, it would
be easier to learn and digest because so much more of the design would
be obvious (and compiler enforced!).
