Hi

I wanted to understand how I can get the error of GetoptLong::Ambigous  
option. Actually I am having that error but I do not understand why?

I do:

require ‘getoptlong’  
optconfig = [  
[‘–help’, GetoptLong::NO\_ARGUMENT],  
[‘–usage’, GetoptLong::NO\_ARGUMENT],

```
    opts = GetoptLong.new(*optconfig)

```

and many other options and each one is different. So that is why I would  
like how it works.

Thanks

David R.
