Debugging

By default, J4JCommandLine grabs the command line from the operating system. However, there are occasions when you'll want to specify the command line explicitly. That's generally in tests.

To do that, you simply set the value of CommandLineText in the instance of J4JCommandLineBuilder you're using:

var optionBuilder = new J4JCommandLineBuilder( StringComparison.OrdinalIgnoreCase )
{
    CommandLineText = "whatever you want"
};

If CommandLineText holds any non-null or non-empty (i.e., anything other than whitespace), its value will be parsed, rather than the value provided by the operating system.
