This was what I was originally contemplating, along with infrastructure for getopt-style helpers. However, having looked at the "Linux way" of doing things, I'm leaning towards a compromise solution. We have a couple of interesting issues to consider; for example, who gets which arguments when we load a file which contains several modules? Archie - I'd really appreciate a pointer to an example of using the ng_parse code to pick up this sort of data, if you can recommend something to help me get my head around it quickly (I've looked but slid off sideways so far...).

But not because people want to be opponents, rather because the tasks and relationships force people to take different points of view.
