Im trying to parse command line args and then build a struct

Very similar to Pythons docopt utility ->

Up till now, I've been using templates to do all of the work,
but now that I realise I can do it all with functions I might
try that. Then use a mixin template to create the struct with
whatever data is required.
Thanks.
I'm sure I'll be back to bombard ye with questions soon!
Did you try looking into "std.getopt"? It's pretty much the same
thing. It doesn't quite do the "useage/help" thing automatically
though (yet). But, IMO, that's trivial to implement.
It's the parsing of arguments you don't want to rewrite. That's
complicated.
