Pretty cool idea. Are you aware of that in D you can, at compile time, 
parse the doc string and generate a command line parser for that 
particular documentation.

Looking at the git example [1], it seems a bit complicated and verbose 
to use after parsing. To determine which arguments was passed to the 
application.
