As for the parseing aspect of the command line arguments, I have been looking at C++ class librarys that make command line parseing easy.

One such library I have become particulary fond of called CLAP can be found at http://www.cs.bgu.ac.il/~cgproj/CLAP/

There is also one called TCLAP which is based on the origional CLAP, with full template support check here http://tclap.sourceforge.net/
