Suggestions: Using arg parsing lib

[SK2006MC]

We could use an arg parsing lib to do the boiler-plate tasks.
And get automatic -h message.

Foe example the built in <argp.h> lib.

I am Sorry, the argp.h is only available for gnu environment.
Maybe we can use this lib instead:

I will check what libraries are available. It could be an interesting idea. Although I will set it as low priority for now.
